 Ensure the working area at any confined space is free from any Hazardous Gas by
proper Gas testing using the Gas testing instrument.

8.1.2 Materials

 Not necessary for the construction shall be removed carefully and stored neatly for
reinstating after the construction works.
 The material received from the client shall be stored in designated area of store.
 Arrangements shall be made to protect against effects of weather and environment.

8.2 Cable Pulling

 Insulation resistance of the cables shall be checked before laying cables.


 After the test, the end of the cable shall be sealed to prevent the ingress of
moisture.
 Location of the panels / equipment shall be identified.
 Cables shall be lubricated if bends in conduits are encountered in a run to facilitate
drawing in.
 Cables must not be bent to a radius of less than 12 times the overall diameter of
the cable.
 Rollers must be used where cables are installed in an open trench using a pulling
rope and eye; cable rollers are to be used at frequent intervals to support the cables
and must never be more than 3 meters apart.
 The rollers are to be placed securely to prevent movement.
 The pulling rope must be equipped with a swivel and be attached to the cable by
a stocking grip with pulling eye.
 The cable drum intended for cable pulling shall be identified as per that indicated
in the drum schedule.
 The cable drums shall be un-packed and placed on a cable roller, as required.
 Cable laying will generally start from one end of the route length or at any suitable
point, as necessary.

 Depending on the weight and size of the drum, suitable size of the cable rolling
shaft (Spindle) shall be placed inside the central axis of the drum.
 Suitable jacks shall be placed firmly on the ground and jacked-up to allow
clearance from the ground depending on the size of the cable drum.
 The drum shall be lifted by required equipment and placed on the jacks.
 The cable drum will be correctly positioned and the direction of cable pulling as
indicated by arrow on the drum shall be complied.
 The cable shall be drawn into the trench smoothly with a minimum of stops and
at an average speed of between 9-12 meters per minute, to avoid irregular
movement.

8.3 Cable Termination & Installation

 Termination point inside the panels / equipment shall be considered for suitable
spare length to be left available during pulling of cable termination.
 After cutting the cable to the required length the termination work will be
conducted as per ADDC Standard.
 Jointing and Termination will be carried out as per ADDC standards. All jointing
and termination work will be carried out by trained technicians, experienced in
such work for the operating voltage concerned.
 Proper crimping tools shall be used compression type lugs. All cables are to be
terminated used glands of proper type and size as per area classification.
 The gland shall be assembled strictly in accordance with manufacturer’s
instruction, particular attention being paid to ensure good mechanical and
electrical contact between parts without excessive strain or distortion of cable.
 The entire body of the cable must enter the gland. The cable shall be on a straight
axis from a point at least six diameter before entering the gland. Seals shall be
checked for correct size at the point of application.
 Unused cable entries shall be closed with plug suitable for the degree of protection
classification.
 After completion of indoor and outdoor termination the cable is ready for Testing.

8.4 Testing & Commissioning

 The following calibrated testing instruments will be used:


 1 KV / 5 KV IR Test Kit - 1 no.
 Multi Meter - 1 no.
 Continuity Tester - 1 no.
 Continuity Tester - 1 no.
 Torque wrench - 1 no.
 VLF - Test Kit

 Before starting the test, the corresponding Circuit Breakers at both ends of the
cables are racked out and earthed properly.

 Test will be conducted at the MV panel end. The opposite end of the cable
termination will be secured & protected. Testing engineer will be at the end where
high voltage is applied and another Engineer to monitor at the opposite end of the
cable.
 Insulation Resistance will be done first: (a) between termination lugs; (b) Phase,
Neutral and Earth termination lug; (c) conductor to termination lug. This will be
done one minute each at 5kV, and the results are noted as per approved test report
format.

Note: The cables and conductors must discharged per test.


 The continuity test and phase sequence tests would be carried out and results
would be recorded for records and future reference.
