The company's compact substations, user-side energy storage systems, complete high- and low-voltage switchgear, small distribution enclosures, compact busways, cable trays, EV chargers and industrial automation control equipment are well regarded across China and exported overseas.
Product description
Our busway range was developed by incorporating advanced technologies from comparable domestic and international products. Its technical performance reaches international levels. Combining the advantages of compact and air-insulated busways, more than ten types of trunking units, tap-off boxes and matching components form a complete three-phase four-wire or five-wire distribution system for different environments and applications.
This product applies mainly to the use of chemical, metallurgical, mechanical, cultural, stadium, exhibition halls, archives, museums, public places such as airports, stations and the sharing of electricity and fire-fighting systems such as high-rise buildings. In normal (non-fire) conditions, electricity can be reduced; in case of fire, the normal power system can be cut off, and fire power can be provided at rated currents, thus achieving normality, and both fire and electricity can be used at reduced cost.
Live busbars are fixed inside an earthed metal enclosure, with flame-retardant insulation between phases and to earth. Stable electrical and mechanical performance and an intelligent temperature-monitoring alarm support safe, reliable operation. Tap-off boxes allow branch circuits to be connected or disconnected while the busbar remains energized, facilitating installation and maintenance. Horizontal, vertical and intersecting layouts provide orderly, standardized wiring. The system is widely used for feeder and distribution circuits below 1000V at 50Hz-60Hz in high-rise buildings, multistory factories, large exhibition centers, hotels, commercial buildings and supermarkets. Enclosed busways are a preferred trunk distribution option in high-end hotels and large commercial buildings to improve supply safety and reliability and reduce faults.
The busway is suitable for ambient temperatures from -20°C to +40°C, relative humidity no higher than 90%, and altitude no higher than 2000m. The installation must be free from strong vibration or impact, explosion hazards, rain or snow ingress, and substances that corrode metal or damage electrical insulation. Conditions outside these limits must be agreed between the user and the manufacturer.
