Brief description of the cable wire power PPV PPV, flat base with a separation according to GOST 6323-79, is a stiff mounting for electrical circuits with a rated voltage of 450 V (for networks 450/750V) frequency to 400 Hz or DC voltage of 1000 V. The design of the wire conductor PPV PPV is available with 2 or 3 copper annealed conductive wires according to GOST 22483-77. Single-wire conductor has a cross section of 10 mm2. Insulation is made of PVC plastic in white, gray, yellow, orange, red, pink, blue, green, brown, black, purple or yellow-green tsvetov.Tehnicheskie and performance power wires cable PPV is designed to operate at an ambient temperature of -50 C to +70 C and relative humidity to 100% (at +35 C). Limiting long-term exposure temperature heating cables in a live operating conditions of + 70 C. Specific electrical resistance wire strands at 20 C not more than 0.01724 ohm mm2 / m, the electrical resistance of insulation at 20 C is not less than 1000 ohm / km at acceptance and delivery and no less than 10 ohms / km for the period of operation and storage of the wire. Installation of cable PPV is at or below -15 C, minimum bending radius is 10 Dn (where Dn – outer cable diameter).
Building wire length PPV – not less than 100 m. The wires with a cross section up to and including 10mm shipped in coils, wires with a section of more than 10mm – on drums. The service life of these wires during normal operation is 15 wire cables let.Sfera of power PPV used for distribution of electric energy in power and lighting networks with stationary and nonstationary pads indoors and outdoors. Some brands allow wires hidden pad under a layer of plaster. With a single gasket wire PPV flame retardant.
