Main Features
  • Dimensions

    The outer diameter of the wire is (3.0 ± 0.1) mm, with a tensile strength between 180-200 Newtons.

    The inner layer consists of two wires, each with a polypropylene ethylene (PPE) insulation layer, with a diameter of (1.0 ± 0.05) mm and a tensile strength between 90-110 Newtons.

    The core wire of the inner layer conductor is made of galvanized or tin-plated steel with a diameter of (0.52 ± 0.02) mm and a tensile strength between 70-110 Newtons.

    The minimum thickness of the external insulation layer should not be less than 0.25 mm.

  • Material:PVC

    Tensile Performance: At temperatures between 16°C and 35°C, using a wire no longer than (600 ± 200) mm, gently lift a 15 kg weight and maintain it for 1 minute. The core wire must not break, and the plastic insulation layer should not crack.

    Low-Temperature Flexibility: After being cooled for 2 hours at a temperature of (-40 ± 2) °C, the wire should be wound around a rod with a diameter no greater than 4 mm, repeated twice. The plastic layer should not crack, and the core wire should not be exposed.
