Plug-in Cable Connector
Plug-in Cable Connector
Plug-in cable connectors are specialized devices designed for the connection of electrical cables in medium-voltage power systems. They can be easily installed and removed, making cable connection, maintenance, and replacement more efficient. These connectors are widely used in electrical equipment such as transformers, ring main units, and cable distribution boxes.
Key Features:
The Plug-in Cable Connector adopts a fully insulated, fully sealed, and fully shielded structure. It is easy to install and supports quick connection and disconnection. With waterproof, moisture-proof, corrosion-resistant, electric-shock-resistant, and aging-resistant features, it provides reliable insulation performance in medium-voltage power systems. Its compact structure helps save installation space and reduce on-site construction time. It is suitable for switchgear, box-type substations, ring main units, and other electrical equipment, making it a safe, efficient, and maintenance-free cable connection component.
Why Are Plug-in Cable Connectors Used?
Plug-in cable connectors are used for the safe and reliable connection of cables in medium-voltage power systems. They provide secure, waterproof, and fully insulated connections, with features such as a semi-conductive outer layer for shielding, a stress cone structure for electric field control, and sealed insulation for maintenance-free operation. They are suitable for medium-voltage cable systems up to 35kV and are widely used in switchgear, distribution cabinets, ring main units, box-type substations, and other electrical equipment.
Product Advantages
Safety: Plug-in Cable Connectors are designed with full insulation and sealing, supporting safe and reliable cable connection in medium-voltage power systems.
Waterproof Performance: The fully sealed connector structure helps prevent water ingress, moisture, and contamination, ensuring stable performance in outdoor and harsh environments.
Protection: With fully shielded insulation and reliable electric field control, the connector helps improve operational safety and reduce cable connection risks.
Flexibility: These plug-in cable connectors support flexible installation and removal, making them suitable for T-type cable connections and expandable distribution systems.
Operating Conditions
Voltage Rating: Suitable for medium-voltage systems up to 35kV, with a continuous current rating of 630A and overload capacity of 900A for up to 8 hours.
Cable Type: Compatible with polymer-insulated cables such as XLPE and EPR, with copper or aluminum conductors, and cables with semi-conductive or metallic shielding.
Environmental Conditions: Can operate in wet or harsh environments, providing reliable performance even in underwater or difficult installation conditions.
Installation Flexibility: Can be installed vertically, horizontally, or at different angles without the need for special tools.
Application
The Plug-in Cable Connector features complete insulation, full sealing, quick installation, and high safety and reliability. It is mainly used in 10kV, 35kV, and other medium-voltage switchgear, ring main units, box-type substations, cable branch boxes, European-style box transformers, American-style box transformers, and other medium-voltage power distribution equipment. It is widely applied in urban power grids, industrial parks, commercial buildings, data centers, subways, airports, ports, and other power distribution systems that require fast, safe, and reliable connection of medium-voltage cables.
