CABLE
GENERAL
Cables specified herein are
suitable for conducting direct current in aggressive environments exposed to
acid, alkali, chlorine and bacteria attacks.
All cables are single core
stranded annealed copper cables, suitable for DC use and double insulated /
sheathed and Armoured to withstand the prevailing chemical and mechanical (soil)
conditions.
All cables supplied are in
600/1000V grade.
The following are cables that
we supply:
Cable
Sheath Abbreviations and General Description
PVC
(Polyvinyl Chloride)
is available in many compound forms
but those for cable making are plasticised to permit extrusion techniques and
subsequent flexibility.
PE
(Polyrthylene)
is available in various forms, the
most widely used description being "low and high" density, with
additional designations to denote the Melt Flow Index (M.F.I).
XLPE
(Cross Linked Polyethylene)
Cross linked polyethylene is a
compound form of PE which enhances the mechanical stability. Most cathodic
protection cables from size 10mm and above uses this type of sheath.
PVF
(Polyethylene Fluoride a.k.a Kynar)
is a high performance, mechanically
strong fluorocarbon, having excellent chemical resistance and are thus ideal
for deep groundbeds and feederes to underwater anodes. Especially recommended
in Chlorine environment.
HALAR
an alternative to PVF with high
chlorine resistance and with a particular application for deep groundbeds.
HMWPE
(High Molecular Weight Polyehyltne)
High molecular wight polyethylene
compound provides strong resistance to abrasion, crushing, chemicals, oil, moisture, and other elements.
EPR
(Ehtylene Propylene Rubber)
is the most widely used synthetic
rubber in the field of electric cable manufacture. It is thermally set by
vulcanisation and is an excellent flexible dielectric.
CSP
(Chlorosulphonated Polythene/ Hypalon)
is also a vulcanised synthetic
rubber and is used as a mechanical covering (sheathing or jacket) to cable
insulated
with EP rubber.
