Marine, OIL,GAS & Petrochemical Cables |
 |
|
 British Standard Fire resistant Shipwiring cables to BS 7917
Unarmoured 1 KV Power
Used widely on ships, oil rigs, gas platforms and many other places where small bending radii are required and fire resistance to IEC60331 is vital, these cables provide circuit integrity to maintain essential emergency services in the event of a fire.
