Flat the dragging of the moistureproof environment-friendly type of described acid and alkali-resistance oil resistant uvioresistant makes cable, it is characterized in that: described braid adopts the tinned copper wire braiding to constitute.
Flat the dragging of the moistureproof environment-friendly type of described acid and alkali-resistance oil resistant uvioresistant makes cable, and it is characterized in that: the radical of described several conductors is 2 ~ 48.
Compared with present technology, the utility model beneficial effect is embodied in:
1. the utlity model has higher flexibility, bending radius is not more than 2 ~ 4 times of the outside diameter of cable, helps cable laying and installs;
2. the finished cable temperature resistant grade of the utility model reaches 90 ℃, has improved the ampacity and the cable overload capacity of cable;
3. the utlity model has stronger dragging and make speed, speed is 300m/min;
4. environment-friendly modified low smoke and zero halogen silane coupling ethylene propylene rubber is adopted in the insulation in the utility model, and its advantage is: (1) ethylene-propylene rubber has good electrical properties, heat resistance and favorable mechanical performance; (2) ethylene-propylene rubber has cold resistance, and minimum heat resistance reaches-70 ℃; (3) adopt modification low smoke and zero halogen silane coupling ethylene propylene rubber material, the same with the XLPE technology mode of processing plastic, can on common shaped plastics extruder, process, do not need complicated vulcanizing equipment, as long as adopt warm water crosslinking to reach the sulfuration purpose.And have lower cigarette, halogen-free environmental performance.
5. the sheath material in the utility model adopts modification low smoke and zero halogen butyronitrile compound, satisfies acid and alkali-resistance, oil resistant, uvioresistant, protection against the tide, softness and characteristic requirements such as low cigarette, Halogen;
6. the utlity model has anti-mineral oil, fuel oil resistance again, fire-retardant oxygen index reaches 48.
