Bus Groove Fire Resistance Rating
May 09, 2018

The fireproof busbar must withstand a period of fire: an hour to 90 minutes. It is called refractory busbar, as the name implies is used for higher.

Fire requirement, meet the standard of fire resistance grade, fire resistance level should not be lower than grade 2.

The structure of the refractory busbar can be either intensive or air-conditioned, most of which are made of alloy steel, and the product is lightweight and corrosion-resistant.

High fire resistance level. The refractory busbar is made of a fireproof coating, a busbar with a fireproof mica and a refractory insulating material.

The scaffold is made up of. There are many grooves on the bracket, and the bus is placed in the groove and fixed. At one end of the bus slot there is a busbar connection box, in the mother.

There are busbar junction boxes in the slot. Refractory busbar has excellent insulation performance, can be used continuously in normal environment, and can be in fire environment.

For more than one hour, it can be used in high-rise buildings and important facilities. Shanghai qianrui busbar.

And Shanghai rongqin busbar to achieve the national grade one fire resistance grade.

Class 1 fire resistance level: all the busbar components are non-combustible.

Second grade refractory grade: the main building components are not combustible except for the suspended ceiling.

Three levels of fire resistance: roof bearing components are flammable.

Grade 4 fire resistance level: the busbar is not combustible, the rest is combustible and combustible.
