Wire and cable are the main carriers of power transmission. According to relevant national standards, the testing items of wire and cable mainly include electrical and mechanical performance testing. Electrical performance testing mainly includes DC resistance testing, insulation resistance testing, and power frequency withstand voltage testing
Testing products:
Bare wire body products, power cables, communication cables and optical fibers, winding wires, insulated wires, audio cables, video cables, bare wires, enameled wires,
Electrical equipment cables, ribbon cables, electronic cables, network management, power cables, power cables, communication cables, RF cables, fiber optic cables, special cables,
Instrument cables, control cables, coaxial cables Signal cables, insulated cables, fire-resistant cables, flame-retardant cables, power cables, wires, etc
Test items:
Appearance: thickness, outer diameter, structural dimensions, surface, etc.
Combustion performance: vertical combustion (or dripping) of a single cable, vertical combustion of bundled cables, smoke density, smoke toxicity, total amount of halogen acid gas, gas acidity, fire-resistant combustion, halogen-free characteristics, low smoke characteristics, flame retardant performance, etc.
Electrical performance: conductor resistance, insulation resistance, voltage resistance, etc.
Power frequency voltage test, resistivity, dielectric constant, etc.Mechanical properties: insulation and sheath mechanical properties, hardness, tensile properties, tear properties, compression properties, bending properties, impact properties, friction properties, fatigue resistance, etc.
