Fire-resistant symmetric twisted pair data transmission cable KPSVЕVng(A)-FRLSLTx for secure communication

Fire-resistant symmetrical pair twisted cables for data transmission, with single-wire copper conductive cores with cross-section from 0,20 to 2,50 mm², with thermal barrier of conductive cores in the form of winding of two mica-containing tapes, with the number of twisted pairs from 1 to 12 or two parallel-packed pairs, with insulation and sheathing made of polyvinylchloride plasticate of reduced fire hazard with low smoke and gas emission and low toxicity of combustion products, with an additional thermal barrier in the form of a winding of mica-containing tape over the core, with a screen of laminated aluminium foil, designed for operation at voltages up to 300 V inclusive alternating current frequency of 50 Hz.
