(630A, European Standard)

This connector set includes a separable connector that links cables to interface C bushings, like transformers and switchgears, and a rear connector to work as a connector extension. 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.

Features
  • Pass all our factory tests;
  • Meet the requirements of IEC60502-4 and HD629.1 standards;

15kV 630A Bolted Separable Tee Connector

This bolted separable tee connector allows cables to be connected together. It is suitable for electrical system rated 8.7/15(17.5)kV. The tee connector links cables to interface C bushings, like ring main units, cable branch boxes, transformers and switchgears, which ensure insulation and form a ring power network. 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.

Apart from supplying quality separable tee connectors, customization services are provided, for instance, the laser engraving of your company’s logo on the surface of the connector. Once you have ordered, we will carry out production at full steam to ensure swift delivery of the products

15kV 630A Bolted Separable Rear Connector

This bolted separable rear connector is suitable for electrical system rated 15kV with continuous current rated 630A. It cannot be directly connected with equipment or bushings. Instead, this rear connector works as a connector extension, operating in step with another one or the one with surge arrester.

Download
Features
  • Compact design, 100 mm to another connector, suitable for small bushings;
  • No earthing wire, insulation is achieved by rubber and air;
  • This separable rear connector is made of premium EPDM that has excellent electrical properties and outstanding mechanical strength. It also features high resistance to tear, ozone gas, oxidation and corrosion;
  • This bolted rear connector works with good thermal stability and delivers thermodynamic performance. Its marvelous sealing performance allows for underwater operation;
15kV 630A Rear Surge Arrester

Rear surge arrester is used to provide over-voltage protection for electrical equipment. Its special design allows for timely minimization of over-voltage caused by lightning.


24kV 630A Bolted Separable Tee Connector

This bolted separable tee connector allows cables to be connected together. It is suitable for electrical system rated smaller than 24kV. The Tee connector links cables to interface C bushings, like ring main units, cable branch boxes, transformers and switchgears, which ensures insulation and forms a ring power network. 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.
