The Wetwon GM-Z series medium voltage cast resin busway is specifically developed for medium voltage power transmission systems. The cast resin contains non-organic volcanic rock which adds to the insulating effects of the busway when sealing the copper or aluminum conductors. The material offers excellent fire resistance and mechanical strength as well with an expected working lifetime of as high as 60 years.

With an IP68 safety rating, the busway is highly effective at heat dissipation, provides high economic current density, low voltage dropping, low loss and minimized electricity consumption. The busway also features strong overload prevention, and is resistant to water and other corrosive elements. These ducts are commonly installed in nuclear power facilities, data centers, ships, chemical plants and other facilities with potentially harsh environments.

Features of GM-Z Series Medium Voltage Cast Resin Busway
1. Rated voltage 3.6kV ~ 40.5 kV;
2. Environmentally friendly design that is flame retardant, and can effectively prevent the spread of flames while emitting no toxic gases when exposed to extreme heat.
3. With a high IP rating, it can run normally under strong water exposure or submergence for long durations.
4. It resists ultraviolet, electromagnetic interference, fungal corrosion and animal bites.
5. With low voltage drop, the short circuit current value is high. It is waterproof, dustproof and explosion proof.
6. This is a maintenance-free product that has passed rigorous aging tests. It can last for 60 years without maintenance.
7. It has a good seismic performance and can run stably and safely in magnitude 8.0 earthquake
8. IP68 rating.
