Impact of Low Dielectric Jelly on Twisted Pair Copper Cable

摘要

In the changing telecom world, demand for better transmission parameters for value added services with cost effective solution is increasing. With this research for developing lower dielectric materials for insulation and cable filling compounds is going on worldwide. This was instrumental to develop a twisted pair copper cable with low dielectric constant jelly. It is evident that if the dielectric of jelly is lower than the diameter over insulation can be reduced. The reduction in insulated diameter in turn results in overall reduction of the cable diameter and as a consequence consumption of various raw materials with improved Characteristics of cable also reduced. The jelly used has not only low permitivity but also possess excellent properties like low absorption coefficient, high volume resistivity. Low dissipation factor and very good water blocking properties. The use of this jelly results in a cost reduction of around 2%.
