Jelly Filled Cable - High Conductivity Copper, Moisture-resistant Jelly Filling, Uniformly Insulated Twisted Pairs For Enhanced Transmission Performance

Jelly Filled Cable Construction :

Conductor
Each conductor consists of a solid bare round wire of annealed high conductivity copper, smoothly drawn with uniform diameter and resistance.


Insulation
It is insulated with either solid medium/high density polyethylene or Foam Skin polyethylene insulation. The conductor is insulated uniformly in various colours with extremely tight tolerances to help the cable meet the electrical and transmission requirements of specification.

Pairs
Individual insulated conductors are twisted together with a uniform lay to form a pair. The length of the lay of each pair is different from that of the adjacent pair to enable the cable to meet the capacitance unbalance, attenuation and cross talk requirements of the specifications. The pairs have specific colour combination for easy identification.

Units
The twisted pairs are stranded in a single unit of 10, 20 and 25 pairs and wrapped helical with an identification colour binder. For higher pairage cable, a number of units are stranded together to form a super unit. A coloured identification binder is wrapped around the super units for easy identification.

Jelly filling
These units or super units are then laid up to form the core of the cable. During this operation a water-resistant filling compound is introduced to fully fill the interstices of the laid up core. This filling compound acts as a dielectric between the layers and the moisture barrier.
