APPLICATION
Assembling wires with fibrous and PVC insulation are designed for connections of electric devices and equipment at AC nominal voltage up to 380V for cross-section areas 0,12-0,14mm² and at 1000V for cross-section areas 0,2-1,5mm² at frequency up to 10000Hz and DC voltage up to 500V and 1500V accordingly.
МГШВ Tinned copper conductor with fibrous and PVC insulation
МГШВЭ The same, in the screen from tinned copper wires
МГШВЭВ The same as МГШВЭ in PVC sheath
DESIGN
CONDUCTOR - copper wires tinned by 40% lead-tin solder and correspond to:
class 4 for cross-sections 0,12mm², 0,20mm ², 1,0 mm ², 1,5mm ²;
class 5 for cross-sections 0,35mm²; 0,5mm ²; 0,75mm ² in accordance with GOST 22483;
for a wire with cross-section 0,14mm² the design should be 8×0,15 mm.
INSULATION – cores are insulated in opposite directions by two layers of a fiber and by PVC-compound.
STRAND - insulated cores of two- and three-core wires are twisted. Parallel laying down of cores in two-cores wires is allowed.
SHIELD – common shield from copper wires (diameter not less than 0,13 mm) tinned by 40% lead-tin solder covers insulated cores in wires МГШВЭ and МГШВЭВ. Density of shielding braid should be not less than 60 %. Two-core screened wires with parallel conductors are marked by additional index «п».
SHEATH – PVC sheath is applied over the screen in wires МГШВЭВ.
TECHNICAL DATA
The basic electrical characteristics:
Wire МГШВ should pass test on alternative voltage 800V for wires with cross-section areas 0,12mm² and 0,14mm², and 2000V for wires with cross-section areas 0,20mm², 0,35mm ², 0,5 mm², 0,75mm², 1,0mm², 1,5mm² at 50Hz frequency. The wire should be placed in the water during 1 minute without preliminary water immersing. When testing МГШВЭ and МГШВЭВ the voltage is applied between conductors and between conductors and a screening braid without water immersing.
Wires can be used at an ambient temperature up to -40°С.
Wires should be assembled at temperature not below -10 °С.
Heating temperature of cores for a long time should not exceed 70 °С.
The minimum bending radius of a wire at operation should be not less than 10 diameters.
Service life of wires is 15 years.
