1. Scope of application

SWCMC series densely insulated bus ducts are suitable for AC three-phase four-wire and three-phase five-wire systems with a frequency of 50-60Hz and a rated current of 100-5000A. They are used to output power for power supply and distribution systems in factories, mines, enterprises, institutions and high-rise buildings, and are particularly suitable for the renovation of workshops and old enterprises.

2. Structural characteristics

Strong heat dissipation capacity

This series of busbars features close contact between phases and between phases and the housing, allowing them to withstand significant electrodynamic and thermal stresses. They also rapidly dissipate heat generated by the conductive bars, resulting in high current carrying capacity. Joints are secured with insulated bolts and connected using double copper busbars, effectively increasing the joint contact area and significantly reducing temperature rise.

Flexible wiring

This series of bus ducts has flexible and convenient interface settings, can be set up with a large number of sockets, and has strong versatility. When adjusting the position of electrical equipment, there is no need to change the power supply system.

three,Structural characteristics

The bus duct complies with IEC439-2 and GB7251.2-1997.

The bus duct can ensure long-term normal operation at rated current and 110% rated voltage.

The bus duct has passed the dynamic and thermal stability tests according to the data in Table (1), and after the test, the bus duct has no perceptible permanent deformation.

SWCMC-2A series bus duct can withstand 3750V.T frequency withstand voltage and last for 1 minute without breakdown or flashover.

When the rated current is passed through it for a long time, the temperature rise of its conductive parts shall not exceed the values listed in Table (2).
