Description

GENERAL SCOPE

– The LSHF fire resistant CXE/AWA (SWA)/FR-LSHF cables are designed to maintain circuit, restrict the propagation of flames when affected by fire.
– The fire resistant cables are properly used for public facilities, backup power systems, emergency systems, fire alarm systems, sprinklers, smoke detection and extraction equipment, emergency lighting and evacuation systems… rated voltage 0.6/1 kV, fixed wiring.
– Low smoke:  On fire, the cables do not liberate large volume of dense black smoke, improve safety in areas where there are limited means of escape in case of emergency.
– Halogen free: On fire, the cables do not emit any poisonous halogen gases, thus prevent forming of acid, which is dangerous for human being and equipment.

TECHNICAL CHARACTERISTICS

– Voltage level U0 / U: 0.6 / 1 kV.
– Test voltage: 3.5 kV (5 minutes).
– Permissible long-term working temperature for conductors is 90°C.
– The maximum permissible temperature of the conductor when short-circuited for no more than 5 seconds is 250°C.
– Fireproof cable at 950°C for 3 hours.
– Cable meets BS 6387 Cat standard. CWZ.
– Fire-resistant cables have slow fire transmission characteristics so it is difficult to catch fire.
– Cables generate little smoke, do not generate toxic gases during the fire.
– The cable has the ability to turn itself off after removing the fire source.
