FAQ

What is the role of the mica glass tape?

It forms the fire barrier around the conductor and supports the cable design for circuit integrity during fire testing.

What does LSZH mean?

Low Smoke Zero Halogen. The sheath is a thermoplastic halogen-free ST8 compound, with smoke and gas test references listed in the fire-performance table.

Which construction sizes are listed?

The construction schedule covers 2-5 core power configurations and three cores plus earth. Select the exact row for conductor size, diameter and weight.

What mechanical protection does this version use?

ST8 inner covering, steel wire armour (SWA) and thermoplastic halogen-free ST8 outer sheath. Select accessories and bonding for this armour material.

What are the conductor temperature limits?

The stated maximum operating temperature is 90°C and the maximum short-circuit temperature is 250°C for 5 seconds.
