RG7H1M1 medium voltage power cable - Applications

This cable is suitable for the transportation of energy between the substations and large users.
It is particularly suitable in areas with danger of fire equipment on the premises where they are concentrated, frameworks and tools where it is essential to safeguard them.
There is no problem if it is left for free-hanging, or installed in tube or channel.
Laying underground should be made in accordance with Art. 4.3.11 of IEC 11-17.
