TELEPHONE SWITCH BOARD CABLES

Application
Cables used for indoor telephones, telephone Exchanges, satellite telecommunication system, industrial plant Communication system, EPBAX system, closed circuit security systems, in-House telephone wiring and various other equipments involving telephones Standard
Cables are generally made as per TEC Specification No.G /WIR-06/02 or as per customer specification. Construction
Solid annealed tinned/bare copper conductor, PVC insulated cores suitably colour coded for distinct identification, twisted to form pairs laid up, PVC sheathed. Armoured Cables are provided with Galvanised steel wire / strip armouring and then sheathed again with PVC.
Design /Material Options
Conductor : Tinned copper/ Bare copper
Insulation : PVC/PVC/Polythelence
Shielding : Over all shielded / Individual Pair Shielded and over all shielded and over all shielded with polyester backed aluminium tape or fine copper wire braid (manufactured against customer's orders only for economical runs)
sheathing : FRPVC/FRLSH/POLYTHELENCE
Conductor Size Cable : 0.4/0.5/0.6/0.7/0.8/0.9 mm
Configuration : 1p,2p,3p,4p,5p,10p,20p
Buyers
BSNL,C.DOT, Switching Equipment manufactures, contractors of BSNL and C.DOT, every industrial and commercial establishment, construction industry and many more beside the general dealer market.

Salient features for Telephone Cable
» Hard grade PVC insulation is used for long life and stable properties of cables
» Staggered lays of twisted pairs are used to ensure minimum cross talk.
» Sizing and processing of conductor and insulated cores is done in precisely controlled manner on automatic modern machines to have optimum values
of capacitance, capacitance unbalance, image and cross talk attenuation and characteristic impendence.
» Shielding is done to protect from outside/ inter pair interference as per specific needs.
