Fire-resistant symmetrical twisted pair cable KPSSV-Vng(A)-FRLS for data transmission

Fire-resistant symmetrical pair twisting 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 from 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 polyvinyl chloride plasticate of reduced fire hazard with low smoke and gas emission, with an additional thermal barrier in the form of a winding of mica-containing tape over the core, designed for operation at voltages up to 300 V inclusive alternating current frequency of 50 Hz.
