132مجموعة إنهاء الكابلات الخارجية كيلو فولت – الشركة المصنعة في الصين

في نقل الجهد العالي, غالبًا ما تحدد النقطة التي يلتقي فيها الكابل بالعالم الخارجي مدى موثوقية النظام بأكمله. يجب أن يتعامل الإنهاء الخارجي مع الإجهاد الكهربائي, weather exposure, pollution, and mechanical forces—all at the same time. At 132kV Cable outdoor Termination Kit, there is little room for error.

أ 132مجموعة إنهاء الكابلات الخارجية كيلو فولت provides the controlled interface between a high-voltage cable and overhead lines, transformers, or switchgear. While it operates in open air, it must deliver the same level of insulation performance as enclosed systems. لهذا السبب, engineers pay close attention to design details, مواد, and installation practices.

في نفس الوقت, many projects also involve إنهاء نظم المعلومات الجغرافية أو الأنظمة الهجينة. لذلك, understanding outdoor terminations alongside GIS cable termination solutions helps engineers choose the right approach for different environments.

What Is a 132kV Cable Outdoor Termination Kit?

أ 132kV cable outdoor termination kit is a complete set of components used to connect a high-voltage cable to external electrical equipment in open-air conditions.

Unlike indoor or GIS terminations, outdoor terminations operate in direct exposure to wind, مطر, الأشعة فوق البنفسجية, والتلوث. نتيجة ل, they must provide strong insulation, reliable sealing, and long-term resistance to environmental stress.

في الممارسة العملية, the termination creates a smooth transition from the cable insulation (typically XLPE) to air insulation. في نفس الوقت, it controls the electric field at the cable end to prevent discharge or failure.

Relationship Between Outdoor Termination and GIS Termination

Outdoor termination and إنهاء نظم المعلومات الجغرافية serve similar purposes but operate in different environments.

An outdoor termination connects the cable to air-insulated equipment. في المقابل, a GIS cable termination connects the cable to gas-insulated switchgear inside a sealed enclosure.

لكن, both types share key design principles. على سبيل المثال, both must control electric stress, maintain insulation integrity, and ensure reliable conductor connection.

بسبب هذا, engineers often compare outdoor termination kits with GIS cable termination systems, especially when deciding between air-insulated and gas-insulated substations.

Main Components of a 132kV Outdoor Termination Kit

A high-quality outdoor termination kit includes several critical components. Each part plays a specific role in overall performance.

نظام التحكم في الإجهاد

The stress control system manages the electric field at the end of the cable insulation. بدونها, electrical stress would concentrate at certain points and increase the risk of failure.

Manufacturers use stress cones or pre-molded stress control elements to distribute the field evenly.

Insulation Body

The insulation body provides the main dielectric barrier. It allows the cable to transition safely from solid insulation to air.

Silicone rubber is widely used because it offers flexibility, weather resistance, and excellent insulation performance.

Sheds (Weather Protection)

Outdoor terminations include sheds, also known as skirts, along the insulation body. These sheds increase the creepage distance and protect the surface from contamination.

نتيجة ل, the termination can operate reliably even in polluted or coastal environments.

موصل الموصل

The conductor connector links the cable conductor to external equipment. It must provide low resistance and strong mechanical stability.

Proper connection helps avoid overheating and ensures efficient current flow.

نظام الختم

The sealing system prevents moisture from entering the cable. Since outdoor environments involve humidity and rain, effective sealing is essential for long-term reliability.

Mounting Structure

The mounting structure supports the termination and keeps it aligned with the connected equipment. It must withstand wind load and mechanical stress.

Types of 132kV Outdoor Termination Kits

Different project conditions require different termination designs.

Pre-Molded Outdoor Termination

Pre-molded terminations use factory-made silicone rubber components. They offer consistent quality and faster installation.

Because of their reliability, they are widely used in modern substations.

Cold Shrink Termination

Cold shrink terminations use elastic materials that shrink onto the cable after installation. They simplify the installation process and reduce the need for heating tools.

Heat Shrink Termination

Heat shrink designs require heating to fit tightly onto the cable. They are cost-effective but require more installation control.

عند اختيار أ 132kV cable outdoor termination kit, conductor size plays a critical role. It affects electrical performance, thermal behavior, والتصميم الميكانيكي.

Below is a practical reference table covering conductor sizes from 25 ملم² إلى 3000 مم².

Conductor Cross-Section and Technical Parameters

How Conductor Size Affects Outdoor Termination Design

Cable size directly influences termination design.

Larger conductors require stronger mechanical support. لذلك, the termination must handle higher weight and installation stress.

فضلاً عن ذلك, electrical stress distribution changes with conductor size. Engineers must adjust stress control components accordingly.

علاوة على ذلك, higher current leads to increased heat generation. نتيجة ل, thermal performance becomes more important for large cables.

Installation also becomes more complex as cable size increases. Larger cables require careful handling and precise alignment.

Installation of 132kV Outdoor Termination

Installation quality determines long-term performance.

أولاً, technicians prepare the cable carefully, ensuring that insulation layers remain intact. Clean working conditions are essential.

التالي, they install stress control and insulation components. ثم, they connect the conductor and assemble the termination.

بعد ذلك, they mount the termination and complete sealing. أخيراً, testing confirms proper electrical performance.

Advantages of Outdoor Termination Kits

Outdoor termination kits offer several advantages.

They are suitable for open-air installations.
They provide strong resistance to environmental conditions.
They support flexible system design.
They are compatible with various equipment types.

بسبب هذه الفوائد, they remain widely used in transmission systems.

Applications of 132kV Outdoor Termination

Outdoor terminations are commonly used in:

• Overhead line connections
• Transformer connections
• Air-insulated substations
• Renewable energy installations

في نفس الوقت, GIS termination systems are used where space is limited or environmental protection is required.
