Mining Telephone Cable – 10PR 0.64mm² Telecom Multipair Phone Cable PC/PE/SCR/XLPO 10x2x0.64 Phone Cable Blue

Mining Telephone Cable – 10PR 0.64mm² Telecom Multipair Phone Cable PC/PE/SCR/XLPO 10x2x0.64 Phone Cable Blue

This custom shielded multipair telephone cable is specifically engineered for mine communication systems requiring reliable voice and data transmission across multiple channels with robust EMI protection in demanding underground environments.

The cable features 10 twisted pairs of 0.64mm² conductors. Each conductor utilizes PC plain annealed copper Class 1 solid wire with 1/0.90 construction, providing excellent conductivity and mechanical strength for long-distance communication. HDPE (High Density Polyethylene) insulation delivers stable dielectric properties and superior moisture resistance essential for underground mining applications. Core identification follows telephone standard color coding with 10 distinct pair combinations: white/blue, white/orange, white/green, white/brown, white/grey, red/blue, red/orange, red/green, red/brown, red/grey.

Each pair is secured with Mylar binder, followed by an individual AL-PET (Aluminium/Polyethylene Terephthalate Laminate) foil screen with tinned copper drain wire, providing 100% EMI coverage for each communication channel. Non-hygroscopic filler materials maintain core geometry and prevent moisture ingress. The 10 pairs are twisted and assembled with an overall Mylar binder, followed by a second AL-PET foil screen with tinned copper drain wire delivering comprehensive shielding against external interference.

The outer sheath is XLPO cross-linked polyolefin in blue, offering LSZH (low smoke zero halogen), fire retardant, and UV stabilized properties essential for mining safety compliance. Rated -25°C to +70°C with 4kV spark test verification, this cable is ideal for underground mine telephone networks, emergency communication systems, and multi-channel voice communication in hazardous mining environments.

FAQ

Q1: Why are solid copper conductors used for mining telephone cables?

A: Solid conductors provide lower resistance over long distances, superior mechanical strength, and stable signal transmission characteristics essential for reliable voice communication in mine shafts and tunnels spanning kilometers.

Q2: What is the advantage of individual pair shielding on all 10 pairs?

A: Individual pair shielding eliminates crosstalk between multiple phone lines, ensuring clear communication across all channels simultaneously without interference.

Q3: Why is HDPE insulation specified for telephone cables?

A: HDPE offers excellent moisture resistance, stable dielectric properties, and mechanical durability, critical for maintaining signal integrity in wet underground mining conditions.

Q4: What do the telephone standard color codes provide?

A: The 10-pair color code (white/blue through red/grey) enables quick, error-free termination and circuit identification during installation and maintenance.

Q5: Why is XLPO LSZH blue sheath used for mining telephone cables?

A: XLPO provides LSZH safety (low smoke, zero halogen) and flame retardancy essential for underground mining, while blue offers high visibility for easy cable identification in dark tunnel environments.
