Railway power lines | The Art of keeping them STRAIGHT
Whenever you travel in a train you might have seen these hanging weights near the poles and a strange connection of wires near to them. What exactly are they? Why couldn’t they just use a simple conductive wire arrangement similar to the normal power transmission system? Let’s learn about the details of auto tensioning devices.
For safe work on and in the track, the railway overhead line must be disconnected, earthed and short-circuited. This protects people and materials in the event of accidental reconnection and dissipates the inductive voltage that is present at life-threatening levels even after the line has been disconnected. If supply vehicles are also used on the affected track section during the work, profile-free earthing and short-circuiting is carried out. This means that the conductive connection between contact wire and earth is established in such a way that driving is still possible. Work is carried out according to the 5 safety rules. This video shows rules three and four, establishing absence of voltage and earthing and short-circuiting.
Equipment used:
• KP-Test 5R voltage detector, 5-piece
• Single-pole earthing and short-circuiting device
• Contact wire earthing clamp P51D
• Rail earthing clamp R50
• Earthing pole (5-piece)
