Armouring: In case of Armoured cables-

• Bedding of helical lapping of two Polythene tapes applied with overlap to provide mechanical protection to the sheath.
• Armour of double layer of galvanized steel tape of required thickness applied helically with a gap not more than 25 # 10% of the width of tape in each layer. The second tape covers the gap of first tape and overlap aleast 15% on either side.
  Wire Armour can also be supplied if requested.
  
  

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.

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.

• 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: "TERA CAB " Telecom cable 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: A aluminium tape coted 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
