ensured that the cables are run over suitable wooden rollers placed in the trench at
intervals not exceeding 2 meters.
In routing, necessary barriers and spacing shall be maintained for cables of different
voltages in case they lie side by side. Telephone cables shall cross the power cables
only at about right angles and these two shall not run in close proximity. LT cables
shall be bent in radius not less than 12 times their individual overall diameters.
Routes of these cables shall be arrived at on the basis of the relevant drawings and
after consulting the Engineer.
Contractor shall provide all necessary labour, tools, plants and other requisites at his
own cost; for carrying out pumping of water and removing of water from trenches if
required anywhere at the time of execution.
H.T. Cables:
H.T. 11 KV grade suitable rating 3 core XLPE aluminum conductor cable minimum
size 150 mm 2 from PHED supply point to 6.6Kv MCC of pump houses.
Specifications for H.T. Cables:
This specification covers the requirements of high voltage cables and associated
accessories like straight joints and termination's etc. The cable sizes shall be
calculated based on the fault level of the local system. Minimum size of HT cables
shall be 150 mm 2 in case of XLPE cables.
Codes and standards:
1. The design manufacture and performance of the cables shall comply with all
currently applicable statutes regulations, and safety codes in the locality where
