The 15kV Rear Connector, also known as an IEC separable connector, is an essential component in power distribution systems. It is designed for terminating incoming and outgoing lines of RMUs (Ring Main Units), switch cabinets, and cable branch boxes, especially suitable for XLPE (Cross - Linked Polyethylene), PVC (Polyvinyl Chloride), and EPR (Ethylene - Propylene Rubber) cables.
This connector is made of safe and environmentally friendly silicone rubber, which endows it with excellent insulation properties, corona resistance, and tracking resistance. Its reasonable structural design adopts a three - layer post - injection peroxide cross - linking process, effectively reducing partial discharge. With built - in stress control, it can ensure a uniform electric field distribution.
The 15kV Rear Connector can be used in combination with a separable front connector (T - type connector) to provide expansion branches. It supports installation in vertical, horizontal, or any - angle orientations. It matches the C - type bushing in EN 50180 & 50181, and complies with execution standards such as IEC 60502.4 and GB/T 12706.4.
Typical electrical performance parameters are as follows: the rated voltage of the cable is 8.7/15kV, the system voltage is 15kV, the rated current can be 630A or 1250A. It can withstand a frequency withstand voltage (AC) of 39 kV for 5 minutes, with partial discharge at 15kV being less than 10 pC, an impulse voltage of 105 kV, and shielding resistance less than 5000Ω. The applicable cable cross - section ranges from 25 to 630mm².
In conclusion, the 15kV Rear Connector plays a crucial role in ensuring the stable and safe operation of power distribution systems.
