Product Description

Product Model Description
The model is composed of a name and a type code, and its specific meanings are as follows

Product Standards
- JB /T10840-2008 3.6kV-40.5kV High-voltage AC Metal-enclosed Cable tap Changer Switchgear.
- GB /T12706.4-2020 Extruded Insulated power cables and accessories with rated voltage from 1kV(Um=1.2kV) to 35kV(Um=40.5KV) - Part 4: Test requirements for accessories of power cables with rated voltage from 6kV(Um=7.2kV) to 3skV(Um=40.5kV).
Product Features
- According to the national standard requirements, when single-core cables are in normal operation, it is stipulated that the induced voltage at the other end of the metal sheath of the cable should not exceed 60V (or 100V when there are safety measures). To effectively avoid circulating current problems, At the cable joint or at the maximum allowable length of single-point grounding of the cable (the maximum allowable length of single-point grounding for 10kV power cables can be designed as 3.0km), using this product can perfectly solve the above problems.
- It is small in size, does not take up much space, is light in weight, easy to move, does not require a base for fixation, and has no special requirements for the installation environment. It is particularly suitable for use in dedicated cable channels for rail transit.
- The integrated design modular cable sheath protector adopts a large cross-section 400A square wave capacity, fully insulated and fully sealed structure, and seals the protector and high-voltage lead cable as a whole in high-quality insulating rubber material. The high-voltage lead cable is connected to the metal sheath of the power cable, and the grounding terminal is fixed on the grounding copper bar, which is used for overvoltage protection of the cable sheath.
- It adopts high-quality stainless steel materials, which can effectively avoid the problem of rusting due to moisture and also prevent the generation of eddy currents during operation.
- The internal structure is reasonably designed, facilitating installation and maintenance.
