Properties and advantages of low-voltage networks with insulated conductors

LV networks with insulated conductors offer many advantages over lines with bare conductors.

• Voltage drops are reduced thanks to the low value of the linear reactance (0.1 Ω/km instead of 0.35 Ω/km).

• Service quality is improved because :

  • insulated cores are protected from accidental contact with foreign bodies;

  • operations are easier to handle, especially when working at live voltages;

  • in the event of support or suspension fuse failure, the network is temporarily maintained in operation.

• Construction is simplified by the fact that the regulations do not impose minimum horizontal distances from obstacles...
