Constructional & Electrical Performance Data
ESI 09-6 Issue 5 Section 2 – Induced Voltage Control Cable

Chef d'orchestre
0.90mm Tinned annealed copper wire in accordance with BS6360 Class 1.
Isolation
The conductors are insulated with Polyvinyl Chloride Type 02 to BS7655, uniformly twisted together to form a pair with a
maximum lay length of 125mm, and colour coded for identification (See Table 1). Suitable for voltages up to and including
150 Volts (d.c.) and 110 Volts (a.c.)
Cable Formation
2 pair cables are laid up in quad formation.
5 – 100 pair cables are laid up in layer formation.
Ecrans
All cables, if required, can incorporate a screen comprising of an aluminium/PETP tape.
The tape screen is in contact with a 0.80mm tinned copper drain wire.
Enveloppes

Type 1	Unarmoured Multipair Light Current Control cables. Extruded Polyvinyl Chloride sheath to BS7655.
Type 2	Armoured Multipair Light Current Control cables. Extruded Polyvinyl Chloride bedding to BS7655, Galvanised steel wire armour to BS1442 and an extruded Polyvinyl Chloride sheath to BS7655.

Alternative PVC materials producing lower levels of HCL are available on request.
