 VI. Installation and laying of cables: mining signal cable manual 
 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 diameter of the other models 15 times. 
 VII. Cable transport and storage: 
 Cables for water. Land. 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) shall immediately notify the factory repair or sales department.
