PVC sleeving

PVC sleeving of electrotechnical purpose, insulating from polyvinylchloride plastic compound of ГОСТ19034-82, (marks of TВ-40, TВ-40А, TВ-40Т, TВ-50, TВ-60) (the TUBE of PVC, cambric)

Tubes are intended for protection and additional isolation of current carrying elements of various electrotechnical devices working at a pressure 1000 V constant and an alternating current of 50 Hz, in an interval of temperatures from-60 up to 70 degrees of Celsius.
