The КПСЭСнг(А)-FRHF (romanized KPSFNG(A)-FRHF) is a fire-resistant, screened, twisted-pair signal cable manufactured by ENTE LLC (ООО «ЭНТЭ»), a Russian company founded in 2012 and recognized as one of the leading producers of cable and wire products for fire protection and security alarm systems. Produced to ТУ 27.32.13-016-37395223-2020 and meeting fire-hazard class П1б.1.1.2.1 per GOST 31565-2012, the cable is designed for fire and intrusion alarm networks operating at up to 300 V.
It features solid annealed copper conductors insulated with fire-resistant silicone rubber, a mica-containing tape fire barrier with 20% overlap, and a laminated aluminum-foil screen with an underlying tinned copper drain wire for effective electromagnetic shielding. The outer sheath is a halogen-free polymer compound in distinctive orange — complying with the FRHF classification by minimizing toxic gas and smoke generation in a fire.
Operating temperature spans from −50 °C to +125 °C, with installation possible down to −10 °C and humidity tolerance up to 98% at +35 °C. Insulation resistance is guaranteed at no less than 100 MΩ/km.
The cable is available in single-pair through 20-pair and multi-conductor configurations, with conductor cross-sections from 0.20 mm² to 2.50 mm². ENTE ships from stock warehouses in Novosibirsk and Crimea, serving customers throughout Russia and the CIS.
