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.
- 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;
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.
