BS 7917 Shipwiring Instrumentation 657M SW4 Fire Resistant Unarmoured

Fire resistant instrumentation cables provide collective or individual screening through the use of metallic foils and drain wires. Mica glass tape fire barriers provide circuit integrity whilst the oil resistant SW4 Low Smoke Halogen Free sheathing compound ensures protection to both people and property during a fire.
