318B Cable Applications
The 318B is used for panel, conduit and general wiring
applications where there is a requirement for flexibility and in the
event of fire there is a need to minimise the risk from smoke and
toxic fumes but circuit integrity is not required.
318B Features
The 318B cable emits less than 0.5% Hydrogen Chloride (HCI) in
accordance with BS 6425 Part 1 and IEC 60754 Part 1
