Description

Nh-vv refractory power cable

Fire-resistant power cable NH - v. v. product characteristics and USES: this product has high fireproof performance, through direct combustion flame, in a certain period of time is not short circuit and short circuit fault, therefore, when the fire broke out, is beneficial to reduce the loss, low smoke zero halogen type cable to cable, especially suitable for fire requires high power, large buildings, railways, shipping, etc.
