Before installation and use should be free hanging, fully to back twist (avoid cable tie and wave distortion);

Steel rope strengthen core after stripping should be fixed, at the same time should bear their own weight and operation cable tension;

Two bar steel rope strengthen core after stripping should maintain symmetry consistent tension, the tension and average deviation should be less than 5%; The elevator car compression elevator buffer, elevator video line not and pit and car bottom border contact; When installation video cable, power supply interface can not have virtual welding, sealing off and should be fixed LaoShi.

Performance:

Cable conductor long-term allowed working temperature of no more than 70 ℃, laying environment temperature shall not be lower than 0 ℃. Install free suspension length more than 35 m. Movement speed of more than 1.6 m/s, not more than 10.0 m/s running at a high speed bearing element for galvanized soft wire rope. Cable laying installation allows bending radius should not less than 6 times of cable small side.
