Cables AVBbShv with threaded section up to 25 mm inclusive, may not be filled. Technical and operational characteristics of the power cable AVBbShV designed to operate in a steady state at room temperature environment from -50 C to +50 C, relative humidity up to 90% (at 35 C). Limiting long-term exposure temperature core heating cables in the operating mode to + 70 C. The maximum permissible temperature of the core heating cables emergency mode, or in + 80 C for the duration of heating not exceed 8 hours per day and 1000 hours for the entire term of service. The maximum permissible temperature of conductors under short circuit (up to 4 sec) + 160 C. Cables AVBbShv for 10 min. stand the test of alternating voltage 3 kV and 3,5 kV cable with an operating voltage of 660 V and 1000 V respectively.
Laying and installation of cables without preheating at a temperature not lower than -15 C. The minimum bend radius when installing single-core cables brand AVBbShv – 10 Dn, strands – 7,5 Dn (Dn – outer cable diameter). Building length of cables for the main sections of veins: 16 – 70 mm 2 – 450 m, 95 – 120 mm 2 – 400 m, 150 mm2i above – 350 m. The electric insulation resistance, calculated for 1 km length at 20 C for core sections 2.5 – 4.0 mm2 – not less than 10 mw, 6 mm2 – no less than 9 mw, 10 – 240 mm2 – not less than 7 mw. The warranty period AVBbShv cable – 5 years, lifetime – 30 years. Scope Power cable AVBbShv with a rated voltage 0.66 kV and 1 kV is used for laying in dry and wet production areas, in special cable racks in the presence of danger of mechanical damage during operation, and in the ground, tunnels, canals, mines, outdoors. Power cables are designed for vertical and horizontal lines and can be used in areas subject to vibration. Cables AVBbShv are self-extinguishing in a single gasket.
