Pakistan General Optical Cable Specifications Table

General optical cables in Pakistan are manufactured according to IEC 60227-5 and BS 6004/7671 standards, with specifications covering conductor type, insulation, voltage rating, and current carrying capacity.

Key Specifications

Standards Compliance: Optical and general wiring cables in Pakistan follow IEC 60227-5 (PVC insulated flexible cables) and BS 6004/BS 7671 for voltage up to 450/750 V. Conductors are made of high conductivity copper, either solid, circular, compacted, or flexible, conforming to BS EN 60228. Insulation is PVC compound, suitable for a maximum operating temperature of 70°C, with color coding for phase, neutral, and earth conductors.

Conductor and Core Details: Single-core and multi-core options are available. Multi-core cables include an inner soft PVC covering to maintain circularity and prevent adhesion to the outer sheath. Color coding: Black or Blue for neutral, other colors for phases, Green/Yellow for earthing.

Voltage and Current Ratings: Rated for 450/750 V for general wiring applications. Current carrying capacities and voltage drops are calculated according to BS 7671, 17th Edition IEE Wiring Regulations, including correction factors for temperature and grouping. Optical Cable Specifics (PTCL Cables): PTCL manufactures optical fiber cables with various core counts, suitable for telecom and data transmission.

Fiber cables are produced with HDPE sheaths and are available in single-mode and multi-mode configurations. Cable sizes range from 10 pairs to 2400 pairs for copper telecom cables, with optical fibers designed for high-density installations. PTCL's optical cables are suitable for outdoor and indoor installations, with robust mechanical protection and environmental resistance.
