Undamaged trailing cables will isolate miners handling the cable from the hazardous voltages transmitted by the cable. To maintain this protection, the cable must be protected from damage and if it is damaged the damage must be readily detected and repaired. Small nicks and cuts in the cable can easily go undetected with most low- and medium- voltage power systems used today. These small nicks and cuts can expose miners to hazardous voltages.



Two ways to improve the system are:
