Armour:
Armour provides mechanical protection
to the cable. It also serves as an Earth Conductors
(ECC)>
One layer of round wire is applied helically
over the bedding.
Material -
Galvanized round steel wire (GSW).
Galvanized round wire (GSW) along with tinned copper
wires (TCW) for maintaining spacified conductivity
of armour (if required by the customer).
Aluminium round wire armour(AWA) is generally used
for single core ac circuitsas aluminium is a non-magnatic
material and this will reduce losses due to armour.
Oversheath
: Following types may be specified for over
sheating:
General Purpose: Extruded PVC
Type 9 compound as per BS 7655
Mediem Density Polyethelene (MDPE):
Offers higher protection from water
ingress and mechanical abrasion.
Anti Ternite: Termite resistance
can be built in both types described above
by compounding with proper additives.
Reduced Propagation (RP) : Retards
propagation of flame in fire situation
(Oxygen Index = 30)

Barrier Tape :
Material - Polypropylene/PETP tape is used
as a barrier tape over the laid up cores.
Function - Holds the cores together and prevents
them from operating out. It works as separator between
diferent polymers used in cable.
Bedding: Extruded
bedding serves as bedding for the armour and as a protection
for the laid - up cores.
Material - Extruded PVC Type 9 Compounds as
per 7655.
Reduced propagation flame retardant (RPLHCL)/RP PVC
Compound for reduced flame propagation characteristics.
