Interface A Separable Connector
(250A, European Standard)
This separable connector is used for the connection of cables onto transformers and switchgears. It is made of EPDM and an insulation layer will be moulded between the insert and the jacket after being connected to epoxy-resin-coated cables.
- Malfunction indicator is optional;
- Test point is enabled, easy checking of circuit status;
- Pass all our factory tests;
- Meet the requirements of IEC60502-4 standards;
250A Plug-in Elbow Connector
This plug-in elbow connector allows cables to be connected together. It is suitable for electrical system rated 24kV or 15kV with continuous current rated 250A. This elbow connector is especially applicable for connecting the 250A cables of ring main unit built in accordance with European standards or combined transformer that consists of the unit. The cross-sectional area range reaches 35-120mm2
- This plug-in elbow connector is fully sealed and insulated. It is equipped with compression part to ensure steady and reliable performance;
- Voltage test point can also be installed with a monitor or a malfunction indicator that allows for the display of electrical status and malfunction status;
- Cold shrink tubes are used between the end of the plug and cables, which effectively avoids moisture ingress;
- This elbow connector is suitable for interface A equipment;
- It meets requirements of GB/T12706.4 and IEC60502-4 standards;
