Jelly Filled Quad Cable

We are offering jelly filled quad cable, which is designed to suit the precise requirements of the esteemed clients. Jelly filled quad cable offered by us is obtainable at highly competitive rates. Jelly filled quad cables are extensively used for axle counter installations ideal to be used in electrified areas.
key featuresavailable in 4 and 6 quadsarmoured constructionstandards conductor sizes : 0.9mm & 1.4mm diameterapplicationsdirect burial applicationideal to be used on ac systems((earthed or unearthed) for rated voltage up to and including1100 voltsused in dc systems for rated voltage up to and including 1500 volts on earth
construction :
conductor :
each conductor consists of round wire of annealed high conductivity copper.insulation :
each conductor is insulated with solid medium/ high density polyethylene insulation.quadding :
four insulated conductors stranded to form a star quad, two conductors diagonally opposite forming one pair and the remaining two diagonally opposite conductors forming the second pairs of the quad.laying up:
the quads are assembled to form a symmetrical core with a right hand lay. Polyethylene strungs of required diameter may be used as fillers, if necessary, for proper circular core formation.filling and core wrapping :
the cable core is fully filled with water resistant comound which is compatible with the polythene insulation of the conductors. The filled cable core is wrapped with at least one helical or longitudinally polythene tape.poly-al laminate moisture barrier :
aluminium tape, coated with polythene on both sides is applied longitudinally over the cable core with a specified overlap. The taoe is seased and bonded to the inner surface of the polythene sheath.sheathing :
the screened cable core is sheathed with black polythene compound as per bs:6234screening and protection :
the cable core with inners sheathis surrounded by a reasonably close fitted screen of aluminium in the form of wires/strips/welded aluminium tubing. The aluminium screen is wrapped with a single layer of woven tape inpregnated with barium chromate with a specified overlap.intermediate sheath :
further protection of screening is provided bby eztryded pvc/pe sheath over screening.amouring :
the cable is armoured with two applications of galvanized steel tape each applied helically with specified gap. The second tape covers the gap left by tge first tap.jacketing :
the armoured cable is fibally jacketed with black pvc/pe compound meeting the requirement of specification
