Our electricians / engineers are fully trained in all aspects of cable spiking and have received the appropriate health and safety training. This cookie is set by GDPR Cookie Consent plugin. Cable spiking is part of a procedure to positively identify the cable to be worked on at the point of work, which may be a joint hole in the ground somewhere It's a similar thing with LV cables but there may be other cables jointed to the cable or connected loads which diminish the resistance to start with. Position the cable vertically so that it is centered between the apparatus bushing and parking pocket, parallel to, and 6.00 inches (152.0 mm) from the apparatus front plate c) The consent of the Technical Authority / Duty Holder must be obtained prior to spiking. %PDF-1.5 When creating a high voltage line by connecting high voltage cables, it is difficult to keep the cables connected by simply linking them together, as described above.

The load I remember seeing something similar when i was a lad,there were these blokes from manweb isolating a side street where all the houses were being knocked down and they opened up a junction box in the pavement attached 2 heavy leads with a big knife switch on one end and ran it about 10 feet from the box,one of them closed the switch by kicking it and there was a big flash and a bang quite fascinating when you are a kid.Anyway I went and asked what they were doing and apparently they couldn,t locate the fuses for that circuit so the easiest way out was to blow them.must admit I,ve been tempted myself on some old factory boards lol. What you are looking for with the change of core insulation method is a significant change in the resistance before and after spiking, rather than absolute values of resistance.

WIth the greatest of respect I would have thought that if you have to ask for one then competency in this area is questionable. After you spike the cable the amplitude of the signal diminishes significantly downstream of the spiking gun. 1.3 In Electricity North West there are five Approved Spiking Procedures for identifying a high voltage cable: a) Injected Signal b) Elimination of all other cables c) Visual tracing Swalek provide specialist engineering teams to carry out cable spiking on underground cables. Spiking is obviously very destructive. endobj This method is better when you have more than one cable in the ground as it helps you to provisionally ID the cable prior to spiking.
