Product Description

Earth Protection Box


1.Product Introduction of the Earth Protection Box


There are many types of Earth Protection Box, JHX cross connection box is suitable for high voltage (35kV, 66kV, 110kV, 220kV) grade of single core cross-linked cable metal protective layer of cross connection protection grounding, It can limit the increase of over-voltage on both sides of metal sheath and insulating joint, It can control the induced voltage of the metal sheath, reduce or eliminate the ring current in the sheath, and improve the transmission capacity of the cable, prevent the cable sheath from being broken down, ensure the safe and reliable operation of the cable. The box body is made of stainless steel, with high mechanical strength and good sealing and waterproof performance; T2 copper bus-bar is used for the internal terminal board, with small contact resistance and excellent conductivity; The protective layer protector has reliable performance, which can effectively prevent the over-voltage of the cable protective layer and ensure the normal work of the cable. The protector adopts two sealing and one forming, with good sealing performance.

5.Product Qualification of the Earth Protection Box


At present, the main type of cross-linked cable terminals for 110~345kV voltage grade is prefabricated rubber stress cone terminal (prefabricated terminal), and the cross-linked cable terminals for higher voltage grade are silicon oil impregnated film capacitor cone terminal (capacitor cone terminal). Other types of terminals, such as the wrap type used earlier in the 110kV voltage class, are now rarely used. The Earth Protection Box has the characteristics of high mechanical strength, good insulation performance and strong pollution resistance.
