Dimension is constituted with the braiding of copper single line.
The present invention in use has a following superiority:
1, tensile strength is high: the carbon fiber wire added in cable conductor and screen layer, its intensity is 62 times of steel, makes cable
Under the tension force that own wt and external environmental factor cause, it is unlikely to damage, fracture.
2, lightweight: the carbon fiber wire added in cable conductor and screen layer, its density is the 1/4 of steel.
3, warp resistance: the carbon fiber wire added in cable and screen layer, has that pliability is good, endurance, creep resistant, heat
The features such as the coefficient of expansion is little, high-low temperature resistant, tensile strength big (62 times of steel).
4, electric performance stablity is lasting: the carbon fiber wire added in cable conductor and screen layer, due to its endurance, anti-compacted
Become, thermal coefficient of expansion is little, tensile strength is big, so under high tension, cable conductor and screen layer will not draw and attenuate, deform, rupture
Cause electrical property change and can effectively protect electric insulation layer.
5, service life is long: the carbon fiber wire added in cable conductor and screen layer, owing to its pliability is good, tension is strong
Degree is big, endurance, creep resistant, thermal coefficient of expansion are little, high-low temperature resistant, corrosion-resistant, so the unit that protection that can be long-term is within cable
Part and the construction of cable complete, the service life making cable is longer.
