China factory HYA/HSYV Telephone cable Drop Cables

Construction

• Conductor: Solid annealed bare copper 0.40/0.50/0.60/0.90mm as per class 1 of BS 6360 and IEC 60228.

• Insulation: Solid polyethylene as per BS EN 50290-2-23/BS 6234/IEC 60708.

• Twisted Pairs: Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk.

• Cabling Element: Twisted pairs/ Triples/ Quads.

Mechanical and Thermal Properties

• Temperature range during operation (fixed state): -30℃~+70℃

• Temperature range during Installation (mobile state): -20℃~+50℃

• Minimum bending radius: 7.5*Overall Diameter

• Core wrapping: Cable containing more than 12 wires has a polyester tape applied over the cable core prior to sheathing.

• Sheath: PVC TM51 gtade or LSZH compound. Grey, white, cream or black colours are standard.

• Ripcord: A ripcord made of polyamide is placed parallel to the core to facilitate sheath removal.

Applications

This cable is designed to handle low frequency signals for short range applications, suitable for cross connecting individual items of switchboard equipment and to connect exchanges with internal distribution points. This cable is intended to be terminated in insulation/displacement connectors (IDC).
