Other than Ex d certified equipment, any electrical termination box or junction box in plant areas,

whether exposed to the weather or not, shall be additionally protected against ingress of moisture or

chemicals by use of Denso tape around enclosure sealed openings and glands. Lanyard fittings arealso to be protected with Denso tape.

6.2

CABLE LADDERS AND TRAYS

All cable ladders regardless of material type, shall be a minimum of Heavy Duty NEMA 20 Brated, with a minimum wall thickness of 2mm and shall be installed using only manufacturers

proprietary fittings. Heavy-duty cable tray may be used provided only manufacturers proprietaryfittings are used and are installed in a vertical plane with field installations having a maximum

width of 100mm. Selection of material shall be in accordance with Appendix 1 (Materials of

Construction) of this Standard. All fixings and fastenings for cable ladder or tray shall be inaccordance with Section 5.3 of this Standard.

Where the Superintendent stipulates that cable ladder covers are to be fitted, they are to be the

peaked cable ladder cover type for horizontal runs and flat type for vertical runs. Hot dip

galvanised covers shall be minimum 1.6 mm.

All high voltage cables are to be run in dedicated high voltage cable ladders, which are to be fitted

with peaked cable ladder covers.

Cable ladders shall be of the width indicated, installed in the orientation shown and at the plan

location and level as shown on the drawings. In addition to those shown on the drawings or asinstructed by the Superintendent, the Contractor shall provide short spur ladders where more than

three (3) cables run in parallel. All cable ladders shall accommodate the cables required and have a25% allowance for future cabling.

Electrical and mechanical continuity of each cable ladder shall be maintained throughout by theinstallation of appropriate bends, tees, crosses, reducers and splice plates by bonding with 35mm5

copper PVC insulated earthing cable. Every fourth cable ladder joint shall be bonded to structural

steel.

All earth bond connections shall be painted with an epoxy-based paint.

Cable ladder supports shall be open to one side to allow the placing of cables without threading.

Supports shall firmly retain the cable ladder under all wind and other loading conditions. Thesupports shall be provided so as to maintain deflection within the manufacturers tolerances. The

installation shall allow for expansion and contraction of cable ladders. Cable ladders shall not bewelded to supports.

When a cable ladder is run horizontally on its side, support brackets shall be installed under theside of the ladder and through bolted to prevent the ladder sliding off the support. Due to the

reduced resistance to bending, a cable ladder installed on its side will require much closer spacingbetween supports to maintain manufacturers tolerances for deflection, as compared with a cable

ladder installed on its bottom.

Cable ladder rung pitch shall not exceed 300mm. Splices shall provide for thermal expansion and

be capable of location at mid span without strength loss. Fixings that may damage cables shall notprotrude into the cable zone.


12/32


ES-14-902-01



Horizontal and sloping runs of cable ladder shall, unless otherwise approved, be installed to receive

cables on the uppermost face.

Cable ladders shall be installed such that the retention of liquids in any channel or other partthereof, or the flow of fluid from one area into another (such as a switchroom) is not possible.

6.3

CONDUITS

6.3.1 Conduit systems for cable support and/or mechanical protection shall be installed by the

open ended method unless specified by the Superintendent. The length of exposed cable

shall be kept to a minimum. The bending radius between conduits shall be 60mm or theminimum bending radius of the cable, whichever is the larger.

Conduits for fibre optic cables shall be continuous and shall utilise long radius bends witha minimum-bending radius of 300mm.

All fittings and accessories shall be of the same material as the conduit system in use.

Conduits shall be installed in a manner that prevents the accumulation of water at any pointin the conduit. Conduits finishing in junction boxes shall be fitted with a locknut on eachside of the box.

Steel conduits shall be fitted with PVC bushes and shall not be direct welded.

All open ends of conduits shall be deburred internally and externally such that a smoothsurface is presented. Deburring shall be carried out using a tool specifically designed for

the purpose intended.

Surface run conduits shall be affixed by means of 316 stainless steel saddles or 316stainless steel U bolts, fastened at regular intervals of no greater than 850 mm, in

accordance with Section 5.3 of this Standard.

In instances where Unistrut is used for conduit support stainless steel conduit clamps are tobe used.

6.3.2 Either Class 15 ABS conduit or stainless steel tubing (with equivalent wall thickness as

stainless steel conduit) shall be used in all above ground installations, unless theSuperintendent specifies other conduit systems.

6.3.3 The use of PVC conduit shall be limited to underground applications except where

otherwise approved by the Superintendent. PVC conduit shall be heavy-duty electricalorange conduit, in accordance with AS2053 except where exposed to ultraviolet

radiation from direct sunlight.

6.3.4 Steel conduit shall be heavy-duty galvanised steel as defined in AS2053. Its use shall besubject to the approval by the Superintendent.

In non-corrosive environments it may be unprotected.


13/32


ES-14-902-01



In corrosive environments where heavy duty galvanised steel conduit is used it shall have

the ends sealed and be treated with System D paint specification as per CSBP

Engineering Standard Protective Coatings (ES-14-102-12).

Flexible, watertight PVC coated steel conduit with stainless steel flexible conduit fittings

may be used with the written approval of the Superintendent.

6.3.5 Class 12 white PVC conduit shall be used for all fibre optic installations.

6.4

SEALING OF OPENINGS

The Contractor shall provide collars and/or weather hoods where cables pass through walls, floors,roofs or other barriers. During construction all openings shall be temporarily sealed

Following testing and commissioning, all electrical openings into buildings and switchrooms, cable

pits trenches and underground open conduits shall be effectively sealed off against fire, water, airand dust passage, to the satisfaction of the Superintendent.

All floor and wall penetrations shall be formed on both sides prior to sealant being applied. The

finish shall be smooth and excess neatly trimmed off. A removable rigid cover shall be supplied ontop of the floor level.

Sealing materials shall be soft cement for larger diameter underground ducts or conduits and non-ignitable foam, faced with rigid non-combustible material for substation walls and floors.

Materials used shall be to the approval of the Superintendent.
