What Is an Inner Cone Plug-In Termination?

Ан 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.

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

Үүний үр дүнд, inner cone technology can provide a compact solution for:

• GIS switchgear
• C-GIS switchgear
• Эрчим хүчний трансформаторууд

• Railway power systems

The bushing interface must match the termination precisely. Үүний үр дүнд, 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. Гэсэн хэдий ч, 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 кВ хүртэл 500 кВ.

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

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

Important design parameters include:

• Cable conductor diameter
• Дамжуулагчийн хөндлөн огтлол
• XLPE тусгаарлагчийн зузаан
• Кабелийн тусгаарлагчийн диаметр
