This PDK71907 fixed LSZH power cable is specifically designed for permanent wiring in public buildings, marine vessels, and industrial facilities where fire safety, low smoke emission, and halogen‑free performance are mandatory. It incorporates four 2.5 mm² (approx. AWG 14) stranded bare copper conductors – a versatile gauge suitable for single‑phase (L+N+E+spare) or three‑phase (L1/L2/L3+N) AC distribution, as well as dual‑circuit DC power feeds. All conductors are bare copper to ensure high conductivity and minimal resistive losses. PE (Polyethylene) insulation provides excellent dielectric stability, very low moisture uptake, and consistent impedance, making it ideal for humid or damp environments. The outer jacket is extruded from LSZH (Low Smoke Zero Halogen) compound, which meets international fire safety standards (IEC 60332‑1, IEC 61034, IEC 60754) – producing minimal smoke and no corrosive halogen gases during combustion, thus protecting both personnel and nearby electronic equipment. The cable is intended for fixed installation in cable trays, conduits, or trunking, with no continuous flexing required. Typical applications include main lighting feeders, socket outlet circuits, HVAC power supplies, and distribution boards in hotels, hospitals, schools, and ship accommodation areas. By combining bare copper, PE insulation, and an LSZH jacket, this cable delivers reliable, long‑term power transmission with enhanced fire safety and environmental responsibility.

Key Features – Bare Copper Conductors, PE Insulation, LSZH Sheath
Bare copper conductors (4×2.5 mm²) – four stranded bare copper cores for efficient power distribution; 2.5 mm² cross‑section supports up to 20‑25 A (depending on derating), suitable for branch circuits and sub‑mains.
PE insulation – rated -40°C to +80°C; low dielectric constant, negligible moisture absorption, and resistance to seawater, acids, and alkalis, ensuring stable insulation resistance over the cable's lifetime.
LSZH outer sheath – low smoke zero halogen compound; self‑extinguishing, non‑corrosive, and low smoke density; complies with marine (SOLAS) and building (CPR) fire regulations.
Fixed installation design – robust circular profile, easy to pull and clamp; compatible with standard cable glands and terminals.
Color‑coded cores – standard phase/neutral/earth colors (e.g., brown, black, grey, blue or yellow/green) for quick identification and safe termination.
Ideal For
Power distribution in public buildings (schools, hospitals, airports, shopping centers) where LSZH is required by local building codes
Shipboard lighting and general power circuits, particularly in accommodation and public areas under SOLAS requirements
Railway stations, tunnels, and rolling stock auxiliary power wiring
Offshore platform safe zones and living quarters
Industrial control panels and fixed machinery power feeds (e.g., conveyors, pumps)
Any fixed installation requiring a 4‑conductor 2.5 mm² cable with low smoke and zero halogen properties
Conclusion
The PDK71907-4*2.5 fixed LSZH cable offers a safe, durable, and high‑performance solution for stationary power distribution in fire‑sensitive environments. Its bare copper conductors, PE insulation, and low smoke zero halogen sheath ensure reliable transmission, long service life, and compliance with stringent fire safety standards. It is an ideal choice for marine, building, and industrial infrastructure projects.
