Earthing Devices For Rail Power Systems

Earthing devices that meet the highest quality and reliability area a prerequisite for work on overhead lines of electric railways. Pfisterer has been developing and producing earthing & short circuiting devices symbolising quality and reliability with a wide variety of options.

• Earthing and short-circuiting devices for short-circuit currents from 4.9 to 29. kA/s
• Copper earthing and short-circuiting cables can be supplied with cross-section from 25 mm2 to 150 mm2
• Individual conductors can be replaced by the appropriate connecting cluster
• Optimised protection from damage and atmospheric influences on cable ends
• Components suitable for different types of application
• Components dimensioned for high short-circuit currents

Thorne & Derrick also stock and distribute the CONNEX range of medium voltage electrical equipment and cable accessories manufactured by Pfisterer to support the construction and operation of Gas Insulated Switchgear, Transformers & Power Systems – this includes cable connectors, bushings, surge arresters and ancillary substation connection products.

Railway Earthing Devices for Overhead Lines

This railway earthing device is designed for use on overhead catenaries. It can be used for contact wire heights between 4.8m and 6.25m. The use of rail earthing clamp R50 allows non-protruding earthing, thus allowing diesel locomotive operation in earthed conditions.

• 1 contact wire earthing clamp 361 499 001
• 1 rail earthing clamp 363 322 005
• 1 earthing cable 8.5m or 12m long 362 138 138
• 1 suspension hook 360 453 453
• 1 telescopic type earthing pole (two-piece) 362 744 744

Railway Earthing Devices for Overhead Lines

This railway earthing device is designed for mobile use and is suitable for transport in cars and service vehicles of emergency services and fire brigades. The use of rail earthing clamp R50 allows non-protruding earthing thus allowing diesel locomotive operation in earthed conditions. To secure the working site the earthing pole and ratchet cab be removed.
