NH-BV is fire resistance cable, which could work for a period of time when it burns. That means the cable won't be burning when the fire happens, so the loop could work in a period of time.

NH-BV is Cu core fire resistance PVC insulation cable.

Main material: Cu, fire resistance, non-woven fabrics

Executive standard:

NH-BV production is up to GB/T 5023-2008; fire resistance property is up to GB/T 19666-2005. Our cable is also up to GA306-2007.

NH-BV has more one layer non-woven fabric than BV. The use terms and technical parameter are almost alike.

Application:

NH-BV is used as wires on urban function centralized key plants and multi-application key buildings in the industry system. The cable could transit the power normally when fire happens within a period of time so that the emergency fire, rescue and the evacuation jobs could be done to reduce the fire loss.

The cable is divided into A, B class, that is NH-BV-A and NH-BV-B.

A: the cable could work lasting 90 min when in 1000 flame burning.

B: the cable could work lasting 90 min when in 800 flame burning.
