  C) Jelly Filled Telephone Cables  
     
 
  • Application : VF Transmission digital system, Local Network, Public, Private and Industrial.

  • Construction: The Cable is made up of:

  • Standards: Generally Complying to
    • IEC60708-1
    • BTCW 1252

  • Insulation: Solid extruded Polthene insulation grade stabilized. 100% Virign material and coloured as per requirment (As per BS 6234, ASTMD 1248).

  • Pairs: Two insulated conductor of specified colours twisted together with pre-dertermined lay to form a pair. The cross talk is minimized.

  • Units(u): 10/20 pairs stranded and a open helical binder of Polyester / PP/PE Tape of specified colours applied to form a unit.

  • Super Units (SU):
    • Five Nos. - of 10 pairs units twisted together to form-50 pair super unit-OR -
    • five Nos.- of 20 pairs units twisted together to form 100 pair super units.
    • Each super unit have an open helical blinder of Polyester/PP/PE tape of a specified colour for identification.
    • Spares pair added in each super unit as per requirments.

  • Cabling/Filling: For cable above 100 pair cable the required number of super units are stranded to form a cable core. -The cable core is fully filled with jelly ( water resistance compound ) which is compatible with the insulation. -The filled cable core is wrapped with a tape and the flooding compound is applied.

  • Sheath: The cable is sheathed with Virgin black polythene
    compound of grade 03c of BS 6234 and confirming to the requirment of specification.

  • Jacket: The armoured cable in Jacketed Virgin black Polythene as per specification (ASTM D 1248).

  • Identification and Marking: On the finished cable Sheath / Jacket the cable identification & marking is done by embossing/Printing as per the requirement of customer/specification.

  • Quality Assurance: "SAMPERG KABEL" are manufactured with advanced production machines and checked with modern computer test equipments at different stages and QA plan followed to ensure Total Quality.

  • Process: Cables are checked at each stage of production and the process is monitored for consistency and uniformity of quality throughout the production.

  • Screen: Aluminium tape coated both side with polythene is applied longitudinally with overlap over the cable core. The laminated aluminium tape is sealed at the overlap and bounded to the inner surface of the inner surface

  • Raw Material: All raw material used in the manufacture of cables are from established and proven suppliers and same are checked before using in the cable production.

  • Finished Cable: The finished cables are tested fully for Routine tests and Type tests to ensure the excellent quality of each every length of the cables before despatch.
