Description
The HV Busway 40.5kV 30000A is a high-voltage busduct system designed to efficiently distribute electrical power at medium-voltage levels in industrial facilities, substations, and infrastructure projects.
This busway system is engineered to replace traditional cable trays and improve safety, flexibility, and energy efficiency in medium-voltage (MV) networks.
With fully enclosed, insulated conductors, the HV busway ensures low loss, high short-circuit strength, and safe modular connections for modern electric power distribution systems.
GB/T 8349 QLFM isolated phase busway, 10KV — 40.5KV, 1000A-30000A
QLFM Isolated phase enclosed bus duct is a kind of high-current transmission device, which is extensively applied in generator main lead-out wire loop and power station Service/auxiliary Transformers.
The Isolated phase enclosed busway is a large-current transmission device widely used in 50MW and above generator lead- out circuits and factory branch circuits.
Advantages:
- The system can be effectively prevented from the grounding fault caused by moisture, dust and external factors under the protection of enclosure. Short-circuit will be avoided between phases because of isolated phase enclosed structure.
- The conductors inside are all connected with flexible braided straps to eliminate the vibration of connected equipment.
- Current transformer can be set up according to the requirement for the purpose of measurement and protection.
- Through the hydrogen measurement, temperature measurement, and humidity measurement devices, the online temperature, humidity, and hydrogen leakage of the busbar body, the outer casing, and the internal environment of the busbar are intelligently displayed. By controlling the micro-positive pressure equipment, the hot air maintenance device can prevent external dust and moisture from entering the busbar, effectively improve the safety index of the whole set of busbars, and ensure the safety and reliability of the busbar system.
