WDZN-YJY 0.6/1kV Copper XLPE LSZH Fire-Resistant Power Cable

For circuits that must keep delivering current through a building fire — emergency lighting, smoke-extraction fans, fire pump motors, evacuation alarm panels — the cable construction adds a mica-glass tape barrier under the XLPE insulation. The cable continues to deliver rated power for 90 minutes in a 750°C flame test.

Overview

Conductor wrapped in two layers of mica-glass tape, then XLPE insulation, then halogen-free flame-retardant outer sheath. The mica layer is the circuit-integrity element: it withstands fire temperatures that would degrade XLPE alone. Verified to IEC 60331-21 (830°C × 90min) — the standard cited in SEA hospital, transit, and high-rise fire codes for life-safety circuit integrity.

Key Features

90 minutes circuit integrity at 830°C

IEC 60331-21 verified — the standard SEA hospital, metro, and high-rise codes cite for life-safety power circuits.

Triple safety properties

Fire-resistant + flame-retardant + halogen-free + low-smoke in one cable — no need to bundle four products for one project.
