 Installation and laying of cables: 
 1. Cable long-term allowable working temperature of -40 ~ +50 ℃, monthly mean relative humidity of 95% (+25 ℃ pm); 
 2. Cable laying and installation to allow the temperature should be not lower than -10 ℃; 
 3. Minimum cable bending radius: MHYVR type is 10 times the cable diameter, the other 15 times the diameter model. 
 Transport and storage of cable: cable for water landing. Empty of all means of transport, during storage in transit should be noted: 
 1. Cable to prevent water intrusion; 
 2. Prevent serious bending and other mechanical damage; 
 3. Prevent heat and sun exposure; cable laying process, such as the quality of man-made accidents (such as the outer sheath damage) should immediately notify the factory repair or sales department.
