Hi

I have currrently been asked to get the ball rolling on a job that requires changing the path of a 11KV cable. The cable is a 120mm copper type PILC and is expected to be double wire armoured. It is buried in the ground and the new route is expected to go above the ground about 40 foot in the air against a solid wall. Only part of the cable is getting replaced so two pits are being dug and jointed at both ends.

Can anybody please direct me in the right route of regulations that I can look at or any other information I can read up on that may help me with this job.

Any help is much aprreciated!

There is no HV regs book as such, just EAWR and good engineering practice, along with other guides and codes of practice.
The cable has to be heavy enough to do the job, and has to be installed to the makers spec's. Joints must be suitable for the old and new cable. Can the new cable sheath carry the prospective fault current? will the new cable alter the circuit impedance to the extent that the protection has to be reviewed?
Probably the most important consideration is do you have safe working practices in place for this type of job?

Are you controling ths work your self or using a suitable contractor?
