Prefabricated Cable Accessories

The insulating busbar system can be used for the busbar connection between switch cabinets in GIS systems. The suitable minimum center distance is 500mm. It adopts a bolt compression structure, and the flexible connection is insensitive to the height error of the assembled cabinets. The shielded type separable connector is a fully insulated, fully shielded, touchable separable connector. The product adopts a unique production process, with the three-layer EPDM rubber being injection-molded as a whole. The minimum thickness of the insulation layer is 10mm, and the minimum thickness of the outer shielding layer is 3mm. The outer shielding layer has anti-ultraviolet, anti-ozone, and anti-electric leakage marks properties. The insulating plug is made of epoxy resin and is equipped with embedded brass components. The external copper piece is connected to the shielding cap to achieve a fully shielded connection. Remove the shielding cap, and the screws inside the insulating cap can be used for electrical testing. The rear connection of the lightning arrester provides lightning protection and overvoltage protection for electrical equipment. The good non-linear resistance sheet enables the lightning arrester to have a low residual voltage, large current-carrying capacity, fast response time, and flat steep wave characteristics, ensuring the operation of power transmission and transformation equipment. The product is suitable for ring main units, box-type substations, and cable branch boxes that comply with EN 5081 and DIN47636 standards, and is suitable for distribution network systems with cable cross-sections of 35 - 630mm2, voltage levels of 12kV and 24kV. The SPE type lightning arrester adopts a unique disengagement explosion-proof device. Under any grounding method of the neutral point, when the lightning arrester undergoes long-term operation degradation or is damaged by lightning strike, the disengagement device can reliably act. This effectively prevents the lightning arrester from exploding and permanent grounding faults in the power system, ensuring the safe operation of the power grid.
