BS5308 Part1 Type 2
Mica & XLPE Insulated Steel Wire Armored LSZH Jacket Cable
Application:
Instrumentation cables are multi conductor cables which convey low energy electrical signals used for monitoring
or controlling electrical power systems and their associated processes. Instrumentation cables convey signals
from process monitors to process analyzers (usually electronics equipment) and from the analyzers to control
equipment in the electric power system..
Construction:
Conductor:Plain copper wire conductors to BS 6360, class 2 (stranded).
Insulation: Conductors are insulated with Mica fire resisting tape and XLPE
Pair screens: Aluminium/p.e.t.p. Laminated tape applied with the metallic side down in electrical contact with a
0.5 mm 2 tinned copper drain wire.
A 23 micron isolation tape is applied over the screening tape with a minimum 50% overlap.
Collective screen: Aluminium/p.e.t.p. laminated tape applied with the metallic side down in electrical contact
with a 0.5mm 2 tinned copper drain wire over the p.e.t.p. binder tape.
Inner Sheathing: An inner layer of extruded LSZH compound is applied over the cable core.
Armor:Galvanized steel wire
Outer Sheathing: An outer protection of extruded PVC compound is applied over the armour.
Standard:BS5308, IEC60331, BS6387
Packing: The cables are delivered on non-returnable wood drums.
