1.0.4KV Fully insulated closed aluminum tubular busbar
1), Product characteristics of 0.4KV Fully insulated closed aluminum tubular busbar
0.4KV Fully insulated closed aluminum tubular busbar products are suitable for power transmission and distribution in low-voltage power supply system, and are used to replace cables in 10KV substation. The products are divided into three phase four wire system and three phase five wire system, which can be arranged in two layers or arranged in a single layer.
The utility model has the advantages of large current carrying capacity, high protection level, convenient distribution of electric energy, safety and reliability, clear and simple wiring, and is suitable for laying various complex environment spaces. Compared with the dense busbar and cable, it has the advantages of large transmission capacity and small line loss.
It is especially suitable for low voltage distribution system of industrial and mining enterprises and power supply system of high-rise commercial and residential buildings, hotels and hospitals.

2. 40.5kV/2500A Fully insulated closed aluminum tubular busbar
1), Product characteristics of 40.5kV/2500A Fully insulated closed aluminum tubular busbar
40.5kV/2500A Fully insulated closed aluminum tubular busbar products are used to connect transformer low-voltage side bushing with the main switchgear cabinet, and feeder connection between switchgear and switchgear cabinet. The products are insulated and sealed independently.
The whole insulation shield is free from environmental interference and high reliability.
The conducting fluid is tubular, with low skin effect, large carrying capacity, high mechanical strength, large short circuit current and large installation span. It can be directly installed on the frame, eliminating wall bushing and post insulator, and has strong anti vibration capability. Easy installation and maintenance.
