Inner Cone Plug-In Termination Manufacturer

Sebuah Inner Cone Plug-In Termination manufacturer provides specialized cable accessories for connecting high-voltage power cables with GIS, transformator, switchgear, and other electrical equipment. The technology uses a compact plug-in interface and a premoulded stress cone to control the electrical field around the cable insulation.

Compared with conventional cable terminations, the inner cone design offers a compact connection structure. Karena itu, it works particularly well in substations where installation space remains limited. Selain itu, many modern designs use dry insulation technology, which simplifies installation and reduces the need for liquid insulating media.

Inner cone plug-in technology can serve medium-voltage, tegangan tinggi, and extra-high-voltage applications. Depending on the manufacturer and product design, available voltage classes can range from around 10 kv to 500 persegi panjang.

What Is an Inner Cone Plug-In Termination?

Sebuah Inner Cone Plug-In Termination connects a power cable to an electrical apparatus through an inner cone bushing. The system normally includes a stress cone, conductive contact, insulation interface, sealing components, and mechanical pressure components.

The stress cone plays a critical role in electrical field control. It distributes electrical stress around the cable insulation and reduces the concentration of electric field at the end of the semiconductor screen.

Selama instalasi, the cable termination enters the corresponding bushing. The interface then creates a controlled electrical connection between the cable and the equipment.

Sebagai akibat, inner cone technology can provide a compact solution for:

• GIS switchgear
• C-GIS switchgear
• Transformator daya
• Gardu induk berinsulasi gas
• High-voltage switchgear
• Renewable energy substations
• Offshore wind power systems
• Sistem transmisi bawah tanah
• Sistem tenaga kereta api

The bushing interface must match the termination precisely. Akibatnya, engineers should confirm the interface dimensions before selecting an Inner Cone Plug-In Termination manufacturer.

Inner Cone Plug-In Termination Voltage Levels

Voltage rating represents one of the most important selection criteria. Namun, customers should distinguish between the cable’s nominal voltage and the equipment’s maximum voltage.

The following list covers common or potentially applicable voltage levels from 10 kv to 500 persegi panjang.

This table includes commonly used nominal voltages and equipment classes. Namun demikian, not every voltage level represents a standard inner cone product.

Misalnya, some manufacturers offer inner cone systems up to 52 persegi panjang, while other product families cover higher voltage classes such as 72.5 persegi panjang, 145 persegi panjang, 245 persegi panjang, or beyond. Karena itu, engineers should evaluate each project according to the actual cable and bushing interface.

10kV to 52kV Inner Cone Plug-In Termination

Itu 10 kv to 52 kV range represents an important application area for plug-in cable accessories.

Common cable voltage ratings include:

• 6/10 persegi panjang
• 8.7/15 persegi panjang
• 12/20 persegi panjang
• 18/30 persegi panjang
• 19/33 persegi panjang
• 26/35 persegi panjang

At these voltage levels, manufacturers commonly use premoulded silicone rubber stress cones. Silicone provides good electrical insulation and maintains suitable interface pressure over a wide operating temperature range.

Lebih-lebih lagi, the compact plug-in structure allows engineers to install cable connections inside switchgear or transformer compartments with limited space.

Untuk 10 persegi panjang, 20 persegi panjang, 24 persegi panjang, 30 persegi panjang, 33 persegi panjang, Dan 35 kV systems, the manufacturer normally selects the termination according to the cable insulation diameter and conductor cross-section.

Karena itu, customers should provide complete cable dimensions rather than only the voltage rating.

66kV to 145kV Inner Cone Plug-In Termination

Itu 66 kv to 145 kV range enters the high-voltage cable accessory market.

Typical voltage levels include 66 persegi panjang, 69 persegi panjang, 72.5 persegi panjang, 90 persegi panjang, 110 persegi panjang, 115 persegi panjang, 126 persegi panjang, 132 persegi panjang, 138 persegi panjang, Dan 145 persegi panjang.

At these voltage levels, electric field control becomes increasingly important. The manufacturer must carefully coordinate the stress cone geometry with the XLPE insulation, semiconductor screen, and bushing interface.

Misalnya, A 110 kV or 132 kV cable termination cannot simply use the same structure as a 20 kV termination. Higher operating voltage requires greater insulation capability and more precise field grading.

Selain itu, the termination must match the GIS or transformer bushing mechanically and electrically.

IEC 62271-209 provides important requirements for cable connections between high-voltage switchgear and cables. Akibatnya, customers should check the applicable interface standard before placing an order.

170kV to 245kV Inner Cone Plug-In Termination

Itu 170 kv to 245 kV range covers major transmission applications.

Kelas tegangan umum meliputi:

• 170 persegi panjang
• 220 persegi panjang
• 230 persegi panjang
• 245 persegi panjang

Among these values, 245 kV represents an important IEC equipment voltage class.

A high-voltage inner cone termination requires careful control of the interface pressure. The stress cone must also maintain stable electrical performance throughout the service life of the cable system.

Lebih-lebih lagi, the manufacturer should evaluate partial discharge performance, AC withstand voltage, lightning impulse withstand voltage, and thermal characteristics.

Untuk a 220 kV or 230 kV project, the customer should therefore provide the cable construction, Ukuran konduktor, ketebalan isolasi, diameter isolasi, and GIS bushing information.

This information allows the Inner Cone Plug-In Termination manufacturer to select the correct interface and termination dimensions.

275kV to 500kV Inner Cone Plug-In Termination

Applications above 245 kV belong to the extra-high-voltage transmission field.

Potential project voltage levels include 275 persegi panjang, 300 persegi panjang, 330 persegi panjang, 345 persegi panjang, 362 persegi panjang, 400 persegi panjang, 420 persegi panjang, Dan 500 persegi panjang.

At these voltage levels, the termination design becomes considerably more demanding. Engineers must consider the complete electrical and mechanical system rather than the termination alone.

Important design parameters include:

• Cable conductor diameter
• Penampang konduktor
• Ketebalan isolasi XLPE
• Diameter isolasi kabel
• Semiconductor screen
• Stress cone geometry
• Electric field distribution
• Tekanan antarmuka
• Kinerja pelepasan sebagian
• AC withstand voltage
• Impuls petir menahan tegangan
• Switching impulse withstand voltage
• Short-circuit performance
• Kinerja termal
• Mechanical interface dimensions

A 500 kV cable system requires particularly careful engineering. The termination must work together with the cable, GIS or transformer bushing, grounding system, dan lingkungan instalasi.

Karena itu, A 500 kV Inner Cone Plug-In Termination should normally involve project-specific engineering and testing. Customers should not select the product only by matching the nominal voltage.

Why Choose an Inner Cone Plug-In Termination?

The compact design provides one of the main advantages of inner cone technology.

Pertama, the plug-in connection can save installation space. This feature becomes valuable in GIS substations and compact transformer installations.

Kedua, many designs use dry-type insulation. Karena itu, the installation process does not require oil-filled cable connection systems.

Ketiga, the premoulded stress cone provides controlled electrical field distribution. This design helps maintain reliable insulation performance around the cable termination area.

Selain itu, a plug-in connection can simplify equipment connection and future maintenance when the equipment design allows removal of the cable termination.

Namun, the installation team must follow the manufacturer’s instructions carefully. Cable preparation, semiconductor removal, stress cone positioning, contact installation, and interface cleaning all affect final performance.

How to Select an Inner Cone Plug-In Termination Manufacturer

Customers should consider several technical factors when selecting an Inner Cone Plug-In Termination manufacturer.

1. Nilai Tegangan

Confirm the cable nominal voltage and equipment maximum voltage. These two values do not always have the same numerical value.

2. Cable Conductor Size

The conductor cross-section directly affects the termination contact and mechanical design.

Typical conductor sizes can range from small medium-voltage conductors to large transmission cable conductors.

3. Cable Insulation Diameter

The insulation diameter represents one of the most important dimensional parameters. A termination designed for one cable diameter may not fit another cable with the same nominal voltage.

4. Bushing Interface

The inner cone termination must match the corresponding GIS or transformer bushing.

Karena itu, customers should provide the bushing type, interface dimensions, and relevant technical drawings whenever possible.

5. Persyaratan Pengujian

A qualified manufacturer should provide relevant test documentation. Depending on the voltage class, the project may require partial discharge testing, AC withstand testing, impulse testing, thermal testing, and other verification.

6. Dukungan Instalasi

A reliable manufacturer should also provide installation instructions and technical support.

For large transmission projects, installation training can further reduce the risk of incorrect cable preparation.

Different countries use different transmission and distribution voltage systems. Karena itu, an international manufacturer needs to understand multiple voltage standards.

For medium-voltage applications, customers may request 10 persegi panjang, 11 persegi panjang, 12 persegi panjang, 15 persegi panjang, 20 persegi panjang, 22 persegi panjang, 24 persegi panjang, 30 persegi panjang, 33 persegi panjang, 35 persegi panjang, atau 36 kV systems.

North American projects may use 15 persegi panjang, 25 persegi panjang, 35 persegi panjang, 69 persegi panjang, 115 persegi panjang, 138 persegi panjang, 230 persegi panjang, atau 345 kV systems.

Sementara itu, IEC-based transmission networks commonly use equipment classes such as 72.5 persegi panjang, 145 persegi panjang, 170 persegi panjang, 245 persegi panjang, 362 persegi panjang, Dan 420 persegi panjang.

Extra-high-voltage projects may require 400 persegi panjang, 500 persegi panjang, or other project-specific voltage levels.

Sebagai akibat, an experienced Inner Cone Plug-In Termination manufacturer should evaluate the complete project specification before recommending a product.
