The AC trackside solution keeping trains ‘on track’ with reliable power
Nick Tucker, marketing assistant at Hawker Siddeley Switchgear Ltd, discusses the V-Mag 25 – 25kV single phase vacuum switchgear for railway electrifi cation.
Key features
• Weather-proof housing for protection of equipment from both weather and unau- thorised access; • Self-contained room; • Robust construction;
• Complete factory substation assembly; • Fully factory tested, resulting in minimum site commissioning and installation time; • Reinforced glass panels ensure it is pos- sible to visually inspect components within the HV compartment without the need for personnel access into the compartment itself;
• Minimal maintenance due to a reduced number of moving mechanical parts; • Capable of retrofi tting into South Wales Switchgear and GEC housing.
H
awker Siddeley Switchgear’s 25kV single phase vacuum switchgear is installed
on many railway networks throughout the world for railway electrifi cation, meeting the demanding system requirements of today’s international railways.
Based on 1,100mm-wide modular units, the V-Mag 25 is arranged with a high voltage compartment enclosing busbars, vacuum circuit breaker and potential transformer together with a control aisle and annex to accommodate supervisory control equipment, battery and auxiliary equipment.
The basic V-Mag 25 circuit breaker unit consists of a panel-mounted magnetic actuator operated vacuum circuit breaker. This is directly connected to the circuit via the lower busbar, and the top pole is connected to roof
entry bushings. The design is such that it is suitable for both retrofi tting of existing trackside breakers and for completely new switching stations.
The circuit breaker is mechanically interlocked to prevent dangerous or inadvertent operation.
Each circuit breaker comprises a single vacuum interrupter mounted on a post insulator, which also supports the operating mechanism.
The circuit breaker module is removable, complete with mechanism from its service location.

Gurit’s core materials (Gurit Balsafl ex and Gurit G-PET FR)
Gurit’s qualifi ed prepreg materials meet the highest international fi re protection regulations regarding fi re, smoke, toxicity and heat release
Delivering the future of composite solutions to the rail market
Gurit has established itself as a developer and innovator in the composites industry and positioned itself as the leading global supplier of composite materials, engineering services, tooling equipment, and select parts and systems, says Piet Heydorn, its technical sales manager.
W
ith over 30 years of experience as a prime composite materials supplier
and engineering partner to a broad array of industrial markets – including high-end applications such as today’s most advanced passenger aircraft,
award-winning high-
performance boats, prestigious cars or weight- and performance-optimised composite wind turbine blades – Gurit understands the most pressing needs of the rail market.
Modern mass transportation needs to be fast, effi cient, comfortable and safe. Velocity, energy effi ciency and passenger comfort and safety
have a lot to do with the design concept, smart components and the materials employed: the lighter train carriages are, the faster the train can accelerate, move and brake. A lighter train also uses less energy per unit of passenger distance covered. Stronger, more durable and easy-to-clean materials translate into lower maintenance cost over the whole life span of a train.
Passenger comfort also requires lightweight, compact and durable materials, so designers can design train car interiors, or seat structures that off er passengers (amongst other features)
the maximum individual space and leg-room, a friendly and clean environment and excellent noise and pressure protection during high- speed motion.
The key parameters of passenger safety are the fi re, smoke and toxicity performance of the materials chosen. All these aspects can be optimised by using state-of-the-art composite materials and solutions from Gurit.
