PV：
Using electrical conductors fine soft round copper wire or tin plating round copper wire twisted and become, 6 class structure conductor cross section: 0.5-6 was.Performance and appearance conforms to the provisions of GB/T3956-2008.
Conductor surface should be smooth, no pollution, no damage to the insulation of burrs, sharp edges, etc., no single bulge or rupture.
insulation
Insulation is special composite material (PVC), soft quality, abrasion resistant, oil resistant, aging resistant, weather resistance and other properties, but also has high waterproof, moisture permeability, warm, antibacterial, antimicrobial, anti-ultraviolet radiation and many other outstanding features.
Can use color or insulated wire core digital coding.
Insulation nominal thickness shall meet the specified in the Q/AICS007-2012.Average thickness of insulation is not less than the nominal value of regulation, the thickness of the thin insulating layer cross-sectional in office is the most points is not less than 90% of the nominal thickness of 0.1 mm.5.2.4 insulation wire core should undergo spark power frequency withstand voltage test without breakdown, withstand voltage shall comply with the stipulations in the Q/AICS007-2012.
cabling
Insulation wire core (1-37 core, special specifications according to customer request production) in order to right twisted together, cabling pitch length is not more than 16 times the diameter of the core, and the pitch should be uniform.
Cable into cable filler material adopt non hygroscopic material filling roundness, cabling, cable conductor outside using a layer of non hygroscopic belt around the wound tight.
sheath
Sheath using polyurethane (PUR) elastic sheath material, sheath smooth surface, thickness of sheath conform to the stipulations of the Q/AICS007-2012, as a minimum thickness of not less than 85% of the nominal value - 0.1 mm;Performance in accordance with the rules of the Q/AICS007-2012.
Finished goods inspection
The finished cable should be able to withstand a 3 kv ac voltage, 5 minutes insulation breakdown does not occur.
The finished cable conductor dc resistance test conducted on each length of cable conductor, the test results should comply with the regulations of GB/T3956-2008.
