Inner Cone Plug-In Termination Manufacturer

ان Inner Cone Plug-In Termination manufacturer provides specialized cable accessories for connecting high-voltage power cables with GIS, محولات, المفاتيح الكهربائية, 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. لذلك, it works particularly well in substations where installation space remains limited. فضلاً عن ذلك, 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, الجهد العالي, and extra-high-voltage applications. Depending on the manufacturer and product design, available voltage classes can range from around 10 كيلو فولت ل 500 كيلو فولت.

What Is an Inner Cone Plug-In Termination?

ان 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.

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

نتيجة ل, inner cone technology can provide a compact solution for:

• GIS switchgear
• C-GIS switchgear
• محولات الطاقة
• محطات فرعية معزولة بالغاز
• High-voltage switchgear
• محطات فرعية للطاقة المتجددة
• Offshore wind power systems
• أنظمة النقل تحت الأرض
• أنظمة الطاقة للسكك الحديدية

The bushing interface must match the termination precisely. بالتالي, 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. لكن, 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 كيلو فولت ل 500 كيلو فولت.

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

على سبيل المثال, some manufacturers offer inner cone systems up to 52 كيلو فولت, while other product families cover higher voltage classes such as 72.5 كيلو فولت, 145 كيلو فولت, 245 كيلو فولت, or beyond. لذلك, engineers should evaluate each project according to the actual cable and bushing interface.

10kV to 52kV Inner Cone Plug-In Termination

ال 10 كيلو فولت ل 52 kV range represents an important application area for plug-in cable accessories.

Common cable voltage ratings include:

• 6/10 كيلو فولت
• 8.7/15 كيلو فولت
• 12/20 كيلو فولت
• 18/30 كيلو فولت
• 19/33 كيلو فولت
• 26/35 كيلو فولت

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.

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

ل 10 كيلو فولت, 20 كيلو فولت, 24 كيلو فولت, 30 كيلو فولت, 33 كيلو فولت, و 35 kV systems, the manufacturer normally selects the termination according to the cable insulation diameter and conductor cross-section.

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

66kV to 145kV Inner Cone Plug-In Termination

ال 66 كيلو فولت ل 145 kV range enters the high-voltage cable accessory market.

Typical voltage levels include 66 كيلو فولت, 69 كيلو فولت, 72.5 كيلو فولت, 90 كيلو فولت, 110 كيلو فولت, 115 كيلو فولت, 126 كيلو فولت, 132 كيلو فولت, 138 كيلو فولت, و 145 كيلو فولت.

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.

على سبيل المثال, أ 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.

فضلاً عن ذلك, the termination must match the GIS or transformer bushing mechanically and electrically.

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

170kV to 245kV Inner Cone Plug-In Termination

ال 170 كيلو فولت ل 245 kV range covers major transmission applications.

تشمل فئات الجهد المشترك:

• 170 كيلو فولت
• 220 كيلو فولت
• 230 كيلو فولت
• 245 كيلو فولت

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.

علاوة على ذلك, the manufacturer should evaluate partial discharge performance, AC withstand voltage, lightning impulse withstand voltage, and thermal characteristics.

ل 220 kV or 230 kV project, the customer should therefore provide the cable construction, حجم الموصل, سمك العزل, قطر العزل, 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.

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
• المقطع العرضي للموصل
• سمك العزل XLPE
• قطر عزل الكابل
• Semiconductor screen
• Stress cone geometry
• Electric field distribution
• ضغط الواجهة
• أداء التفريغ الجزئي
• AC withstand voltage
• دفعة البرق تحمل الجهد
• Switching impulse withstand voltage
• Short-circuit performance
• الأداء الحراري
• Mechanical interface dimensions

أ 500 kV cable system requires particularly careful engineering. The termination must work together with the cable, GIS or transformer bushing, grounding system, وبيئة التثبيت.

لذلك, أ 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.

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