General Introduction
LMC-3A AL s hell busbar channel is used in the system of3 phases,4 wires,3 phases 5wires,50-60Hz, with ratedcurrent 100-5000A power suppy and distributuion, as a schemeof low cost and high efficiency for industrial factories, hospitalstotes, highrise buildings and those environment with high- techto achieve good cost performance.
General Introduction
Smallsize，goodfiexibility
Close sandwich type of structure saves space, and has good performance of reducing voltage. E ach functional unitwhose anale and height can be chanaed, can be installed in interlaver, alonaside wall and other architecture.
Convenientandfast connection
1、 Cone insulation plate reinforces mechanical strength, the modularized shell guarantees pressure without sharp adge2、Big scale bowl type manganese steel washer guarantees contact face even pressure.
3、 Common 19 wrench can fix double heads single bolt with red indication, if the red indication fall off, we can judge thatthe connection joint is fixed without any other testing tols.
4、Bolts can be reused during maintenance.
5、The joint has adjustable place of ± 16mm.
Full Al shell
1、 The shell is full close Al which is light and modularized, the special structure is fit for any installation place withoutthinking of any coefficient of reducing capacitance.
2、Sprayed full Al shell withstand 1000 hours of salt mist test.
3、Full Al shell features dust-proof performances aood ventilation.and electric conduction
Good electric conduction and insulation
1、The busbar adopts good copper and aluminum coated with tin or silvery, so the coating features good protection of anti-corrosion.
2、The conductor is wrapped by B calss (130%) Mylinex, which is insulative.
3、Adopt environmental protection insulative material, which is ROH required SGS 6 items of physical tests and is UL certified.
Jackboxstructure
1、The knob of jack box is installed in box body neck or side place, clear indication of switch on/off is provided.
2、Interlock mechanism is provided for fault switch on or other activity of getting power without permission.
3、Jack box with special fuse tool to get fuse easily.
4 、Modularized cover prevent ginger contact conductor unconsciously5、Special contactor is provided for internal earthing and shell earthing.

Ambien ttemperature influence to installation
Busbar channel works in the environment less than 40℃,and it can works continuously with max temperature.
rise of less than 30K under its rated value,and it can work for not less than 2 hours under 120%overload.
lf busbar channel works continuously in environment of high temperature,its capacitance should be reduced,
that is to say,the rated value x proper coefficinet.
