A free moving cable pulling swivel link.A display of the cable pulling tension on the winch (calibrated).Contractors must familiarise themselves with these cable pulling loads before hiring the equipment to ensure that these loads are not exceeded.įor all Cable Pulling applications contractors should use the following cable laying equipment and products: When pulling and laying cables it is important that angles or bends should not be placed too close together otherwise cable pulling tensions will become greater than the manufacturers guidelines during the installation process.īell Mouth Rollers Winch Cable installationĪll cable must be installed not exceeding the manufacturers recommended cable pulling tensions – this applies to low, medium and high voltage power cables. Installation of Cable ductsįor the installation of ducted schemes the use of Black electric cable ducts only (see table below for approved suppliers) are permitted for use.Ĭlients should consider the type of cable ducts intended to use before ordering as excavations will be different depending on which cable duct supplier you use – the minimum cable bending radius must also be considered by referring to the manufacturers specification and selecting the appropriate cable pulling equipment to include cable rollers, socks, drum jacks and cable winches.Įmtelle cable duct range includes a smooth bore type of ducts which have rigid preformed bends at differing angles. ![]() This cable must only enter through the bottom of the cabinet, using the right hand hole, when viewed from the front.ĭuct Seals – contact us for duct sealing solutions and products to provide sealing against water (flood prevention) to copper and ducted low, medium and high voltage power cables. The cabinets are only large enough to house SSE service and connection equipment.Ĭlients must fit own main switches on an inside wall so that the length of interconnecting cable does not exceed 3 metres. The service tubing must be securely coupled to the ‘hockey sticks’. White ‘hockey sticks’ must be used on the outer surface of walls. The preformed ‘hockey sticks’ can be installed either within the cavity or clipped to the outer surface of the wall below the meter cabinet. The external meter cabinets must be positioned in agreement with SSE to provide unrestricted access. The service tube can be laid in the same cable trench as the other services are shown, with an identifying plastic cable marker tape installed above to give advanced warning of service cable location on private property. New Housing Service Cable Installation GuideĮxperience has shown that by using a service tube the disturbance to the site is reduced when the electricity supply is connected. Please note: Where there are sudden changes in surface type (e.g footway to carriageway), excavations should always be at the greater of the depths required. Please note that (M) represents the cable marker tile ( for 33kV cables use Stokbord covers) or cable protection tape for all other installations including 11kV cables and cable joint protection. Minimum Excavation depth required = (A) minimum depth of apparatus + (B) outside duct/cable size + (C) 75mm of sand bedding. This table shows the minimum depths to top of apparatus (A within the diagram above) Minimum Apparatus Depth Cable marker tape or cable tiles/covers must be installed 150mm above the top of the apparatus, this needs to have SSEN branding on. In addition to the cable or duct there is a requirement for 75mm finefill material on all sides. The following cable trench section shows the position of cable and the cable duct in the ground – it is important that the top of any apparatus is at these depths as a minimum, this includes the top of the cable duct. ![]() It is also recommended that contractors and clients review the ‘Practical Guide to Streetworks’ before undertaking any excavations prior to installing LV-HV cables to form part of new connections. The cable pulling equipment for ensuring safe and compliant installation of LV-HV cables up to 33kV is briefly outlined – should you require any further information or technical support please contact us.Īll work carried out and cable pulling equipment used must be compliant with SSE technical guidance (TG-PS-881) available from the SSEN website. The following information based upon a document produced by UK DNO, Scottish & Southern Electricity Networks, provides information and guidance on New Connections and best practise for cable pulling and laying and when installing LV (Wavecon | Concentric), 11kV (3 Core | Single Core) and 33kV (Single Core) cables into underground cable trenches. ![]() by Chris Dodds T&D - estimated reading time 2 minutes.Thorne & Derrick | Cable Pulling & Laying Equipment Stockists and Suppliers
