Detection range: Wire and cable manufacturers Bare wire system products, power cables, communication cables and optical fibers, winding wires, insulated wires, audio cables, video cables, bare wires, enamelled wires, cables for electrical equipment Cable, electronic cable, network management, power cable, communication cable, radio frequency cable, optical fiber cable, special cable, instrument cable, control cable, coaxial cable, signal cable, insulated cable, fire resistant cable, flame retardant cable, wire, etc. Inspection items: Appearance: appearance, size, printed mark, insulation thickness, insulation thin point thickness, wire and cable have corresponding standards in terms of dimensions and marks, dimensions and marks occupy a large proportion in the cause of nonconformity.

Physical property test: pressure test, elongation change rate, tensile strength change rate, elongation at break. Wires and cables are exposed to the natural environment for a long time, and the mechanical properties and aging detection of wires and cables are particularly important.

Electrical performance testing: resistance test, insulation resistance test, power frequency voltage withstand test, impulse voltage test, conductive resistance, insulation resistance for wire and cable performance testing main entrance examination conductor DC resistance test, insulation resistance test, power frequency voltage withstand test, impulse voltage test, etc.

Aging properties: elongation at break after aging, tensile strength after aging, elongation at break before aging, tensile strength before aging. Wire and cable long-term exposure to the natural environment, the level of reliable performance directly determines the service life of wire and cable. Through aging detection, the service life of wire and cable can be well determined.
