Mining Cable Custom Hybrid Cable Purple – 1PR 4mm² + 1PR 1.5mm² TC/PE/SCR/PVC/XLPO Composite Cable

Mining Cable Custom Hybrid Cable Purple – 1PR 4mm² + 1PR 1.5mm² TC/PE/SCR/PVC/XLPO Composite Cable

This custom hybrid mining cable features two shielded twisted pairs in a composite assembly, engineered for reliable power and signal transmission in demanding underground and surface mining environments.

The 4mm² pair consists of TC tinned copper conductors 56/0.30 with HDPE insulation, twisted together with Mylar tape binder, and individual AL-PET foil screen with tinned copper drain wire for robust EMI protection. The 1.5mm² pair similarly features TC tinned copper conductors 56/0.30 with HDPE insulation, twisted construction, Mylar tape binder, AL-PET foil screen with drain wire, plus an additional PVC inner sheath rated 90°C for enhanced mechanical protection. An overall Mylar tape binder secures the composite assembly, while the purple XLPO cross-linked polyolefin outer sheath provides LSZH (low smoke zero halogen), fire retardant, and UV stabilized properties essential for mining safety compliance. Operating temperature range -10°C to +70°C with 6kV spark test verification, this cable is ideal for mining equipment, tunneling machines, and underground control systems requiring robust, flame-retardant cabling.

FAQ

Q1: What is the advantage of TC tinned copper conductors for mining cables?

A: TC tinned copper provides excellent corrosion resistance in humid and chemically aggressive mining environments while maintaining flexibility and conductivity.

Q2: Why is HDPE insulation chosen for both pairs?

A: HDPE offers low dielectric constant, stable electrical properties, and excellent moisture resistance, ideal for both power and signal applications in wet mining conditions.

Q3: What does AL-PET screen with drain wire provide?

A: AL-PET foil provides 100% EMI coverage for high frequency interference, while the drain wire ensures continuous grounding for effective shielding throughout the cable length.

Q4: Why does the 1.5mm² pair have a PVC inner sheath?

A: The PVC inner sheath adds mechanical protection for sensitive signal circuits, providing additional abrasion resistance and insulation integrity in demanding mining installations.

Q5: What makes XLPO suitable for mining cable sheathing?

A: XLPO (cross-linked polyolefin) provides LSZH safety (low smoke, zero halogen), fire retardancy, UV stability, and excellent mechanical strength, meeting international mining safety standards.
