11.0 LAYING OF CABLES

11.1 11 kV H.T 3 core HT UG cables:

Laying 11 kV HT UG cables by trenchless technology by adopting horizontal directional drilling (HDD) at minimum 2mtr. depth as per site condition using appropriate standard machines. The cable shall be pulled / drawn smoothly in the bored holes by the horizontal boring machine itself. The excavated cable trench, wherever required, shall be drained of all water and bed surface shall be smooth, uniform and fairly hard before laying out the cable. The cable shall be pulled in the trench only on cable rollers spaced out at uniform intervals to prevent damage to cable.

59

The laying out process shall be smooth and steady, without subjecting the cable to abnormal tension. The cable laid out shall be smoothly and evenly transferred to the ground after providing sand cushion and shall never be dropped. All the snake bends in the cable shall be straightened out. 11.2 Loop Cable : One complete loop of the cable has to be kept at each termination point.

12.0 FLAKING

12.1 Wherever it is not possible to lay the entire cable drum length, the cable should be cut and properly sealed and if it is necessary to remove the cable from the drum, it should be properly flaked. Such cable lengths should be properly stored at site.

13.0. CABLE CROSSING OPEN DRAINS WITH LONG SPAN :

13.1 Wherever the cable has to cross open drains with a long span, the cable shall be laid in suitable size G.I. pipe, properly jointed with suitable collars. The GI pipe shall be firmly supported on pillars, columns, or suitable support of R.C.C. foundation with stone masonry in cement mortar 1:4

13.2 Wherever the U.G. cable has to cross the sewerage or water supply line the U.G. cable has to be taken below them, maintaining adequate clearance. Further, wherever the U.G. cable runs parallel to the telephone cable a separation distance of at least 300-mm shall be maintained.

13.3 The cables shall be laid in stoneware pipe wherever the cable and trench crosses private roads, gates, etc. In order to avoid inconvenience the stoneware pipe should be laid first after excavation and excavated trench shall be back filled, compacted and surface properly redone to restore that original condition.

CABLE AND JOINT MARKERS Permanent means of indicating the positions of joints on site should be provided. During the course of permanent reinstatement cable and joint markers, should be laid directly above the route of the cable and the position of the joint respectively.

Wherever it is not possible to place the marker directly over the cable route or joint the marker should be suitably placed near the cable route or joint on which the distance of the cable route or joint at right angles to and parallel to the marker should be clearly indicated.

The position of fixing the markers will be at the discretion of the Engineer-In-charge. 14 . JOINTING OF CABLES

GENERAL: It shall be noted that the U.G. cables are of XLPE insulation and needsspecial care in jointing. The cable jointer and his assistant shall have experience in making joints / terminations. Jointing work should commence as soon as two or three lengths of cables have been laid. All care should be taken to protect the factory-plumbed cap/seal by laying the end solid in bitumen until such time as the jointing is commenced. Jointing of cables in carriage ways, drives, under costly paving, under concrete or

60

asphalt surfaces and in proximity to telephone cables and water mains, should be avoided, whenever possible. JOINT PITS: The joint pits should be of sufficient dimensions as to allow jointers to work withas much freedom of movement and comfort as cables proposed to be jointed requires. The sides of the pit should be draped with tarpaulin sheet to prevent loose earth from falling on the joint during the course of making. The pit should be well shored with timber, if necessary. An overlap of about 1.0 mtr of the cables to be jointed may be kept, for allowance to adjust the position of the joint. When two or more cables are laid together the joints shall be arranged to be staggered by 2 to 2.5 mtr. SUMP PITS: When jointing cables in water logged ground or under monsoon conditions,a sump pit should be excavated at one end of the joint pit in such a position so that the accumulating water can be pumped or bailed out by buckets without causing interference to the jointing operation. TENTS: A tent should be used in all circumstances wherever jointing work is carried out in the open irrespective of the weather conditions. The tent should be so covered as to have only one entrance and the back facing the direction of the wind. The tent cover should be properly weighted or tied down on the sides. MEASUREMENT OF INSULATION RESISTANCE: Before jointing is commenced theinsulation resistance of both sections of the cable to be jointed should be checked by insulation resistance testing instrument. An insulation resistance – testing instrument of 2.5/5 kV shall be used. The Insulation Resistance values, between phases and phase to earth shall be recorded. The actual jointing operation shall start only after the approval of the engineer in charge of works. PRECAUTIONS BEFORE MAKING A JOINT OR CUTTING A CABLE. The cable end seals should not be opened until all necessary precautions have been taken to prevent circumstances arising out of rainy/inclement weather conditions, which might become uncontrollable. The cable seals should be examined to ascertain if they are intact and also that the cable ends are not damaged, if the seals are found broken or the lead sheath punctured, the cable ends should not be jointed until after due examination and testing by the engineer-in-charge of the works. PRECAUTIONS TO BE TAKEN ON LIVE CABLES IN SERVICE Sometimes it becomes necessary that a H.V. cable, which is in service, be cut for making a straight joint with a new cable. In such cases work on joint should start only after the in service cable is properly identified, isolated, discharged, tested and effectively earthed. Search coils interrupters or cable-identifying instruments should be used for this purpose. IDENTIFICATION NUMBERS / COLOURS AND PHASING :The cables should be laidand jointed number to number or colour to colour shown on the core identifying marks and prevent cross jointing. In all cases, the cables should be tested and phased out, and more particularly so when the cable terminates at Ring Main Unit / Sub-station. MAKING A JOINT: The Heat shrinkable joints used shall be conforming to thespecification. Alternatively, push-on or Tapex or cold shrinkable type can be used with the approval of

61

RBI. The contractor should furnish all the technical particulars of these joints and obtain approval only in case they are found superior to the heat shrinkable joints. Epoxy based joints are not permitted. Comprehensive jointing instructions obtained from the manufacturer of joint kits shall be meticulously followed. The connection of the earth wires should be done using flexible bonds connected to cable sheath using clips or soldering. Aluminum conductor strands shall be joined by mechanical compression method, using suitable die and sleeve with a good quality tool. CABLE TERMINATIONS: Cable terminations required are both indoor and outdoor typeand invariably be of heat shrinkable type conforming to the specifications. Alternatively, push-on or Tapex or cold shrinkable type can be used with the approval of RBI with appropriate sheds for rainwater in case of outdoor terminations. All the technical particulars to establish the superiority in the performance of these joints shall be furnished while seeking approval. The instructions furnished by the manufacturer of termination boxes/kits should strictly be followed. Whenever a cable raised from the trench to end in termination, to be finally connected to an overhead line or transformer, the following instructions should be complied with –

I. One coil to be made and left in the ground for future needs II. The rise of cable, immediately from the ground level should be
