It sets the conductor bundle of cable to tinned copper conductor, its stronger electric conductivity, high temperature resistant and corrosion resistant can be utilized
Corrosion ensures the service life of cable；It by the way that inner insulating layer is arranged, and sets inner insulating layer to high density polyethylene (HDPE), has
Stronger electrical property and anti-attenuation ability can effectively prevent conductor to be corroded by the polyethylene foamed of outer layer simultaneously；By insulating
The outer setting external insulation layer of layer further increases the fade resistance of cable using the stronger anti-attenuation ability of polyethylene foamed.
The internal shield wrapped by the way that copper strips is arranged, provides good anti-interference ability, ensures the anti-interference of cable；It is logical
Cross on the outside of copper strip shielding layer be arranged tin-coated copper braided wires as external shielding layer, the two-way shielding having using tin-coated copper braided wires
Effect enhances the anti-interference ability of cable, further protects cable.
By setting the material of sheath jacket layer to LSOH anti-flaming cross-linked polyolefin, handed over using LSOH anti-flaming
When being withdrawn when the performances such as the stronger electrical property of connection polyolefin, low halogen, low cigarette, salt spray proof, mould proof protection cable and generation fire
Avoid the secondary injury of dense smoke；Nylon sheath wire layer is set by the outermost layer in cable, and good pest control mouse can be played
The effect of ant.
