According to the report, the first quarter of 2011, fujian province quality technology supervision bureau organized to fuzhou, xiamen, quanzhou and zhangzhou, south the equal cable production enterprise production of power cable, control cable products for provincial supervision inspection. It is said that, this time selectived examination 12 enterprises 18 batch, qualified 18 batch, batch the qualified rate 100%.
According to information, the supervision inspection according to GB/T 9330.2-2008 "plastic insulation control cable part 2: PVC insulated and sheathed control cable", GB/T12706.1-2008 "rated voltage (1 kV Um = 1.2 kV) to 35 kV (Um = 40.5 kV extruded insulated power cables and accessories, part 1:1 kV rated voltage (Um = 1.2 kV) and 3 kV (Um) = 3.6 kV cable" requirement.
On power cable products sampling project only four: conductor resistance, insulation thickness, insulation the thinnest point thickness, 4 h voltage test 4 projects for inspection. To control cable sampling project many, there were 25 insulation thickness, insulation: the thinnest point thickness, after insulation aging tensile strength, elongation after insulation aging, insulation aging tensile strength rate after, insulation aging elongation rate after, insulating weightlessness test, insulation heat insulation impact test, high temperature stress test, insulation low temperature bending test, insulation low-temperature impact test, the sheath after aging tensile strength, sheath after aging breaking tenacity, sheath after aging tensile strength rate, sheath elongation rate of ageing, sheath weightlessness test, the sheath to thermal shock test, the sheath high temperature the pressure test, sheath low temperature tensile test, sheath low-temperature impact test, the conductor resistance (20 ℃), finished cable voltage test, insulation wire core voltage test, insulation resistance (70 ℃), single vertical flame test 25 project inspection
