Description

1. Product Standard

GB12972-1991 "Rubber-sheathed Flexible Cable for Mining". Flame-retardant cables implement MT818-1999 "Flame-retardant cables for coal mines", and the flame-retardant performance test is implemented according to MT386-1995. For old-type cables and non-flammable cables with flame-retardant requirements, the words "MT386" or "flame-retardant" should be added when ordering.

2. Use characteristics
