RKSS and RKSSP casing pipes made of PVC are non-flame spreading pipes (the fire goes out after removing its source). They are designed to protect electrical installations in construction and industry against: mechanical factors, temperature influences and moisture. RKSS and RKSSP pipes can be laid and poured with concrete (also vibrated). They are characterized by increased resistance to compression (750 N) while maintaining good flexibility. The shape of the longitudinal section ensures trouble-free insertion of wires and cables over long distances. It also guarantees easy access to electrical cables and trouble-free troubleshooting of the electrical installation during operation. Equipped with a steel pilot.
