PWBS - high-current connectors resistant to the most difficult conditions

PWBS – a connector designed for railways
The solution to these problems is the PWBS series of connectors from Radiall VanSystem, designed specifically for the railway industry. PWBS connectors are single-pole connectors with a rated current of up to 1000A, equipped with a secure bayonet system that guarantees reliability and durability even in the most extreme operating conditions.
Their housing, made of durable aluminium alloy, together with a solid stainless steel bayonet mechanism, ensures mechanical durability and reliability for many years of use. PWBS connectors meet the most stringent requirements for fire resistance (compliance with EN45545-2), dust and moisture protection (IP67), as well as corrosion protection (up to 2000 hours of salt spray testing). Special thermoplastic insulators guarantee not only very high mechanical strength, but also a wide operating temperature range from -60°C to +180°C.

Energy efficiency and safety
PWBS also provide effective EMC protection, have touch-proof contacts and feature exceptionally low electrical resistance of less than 0.5 mΩ, which significantly improves energy efficiency and reduces the risk of system failure. The use of accessories such as special cable glands, adapters and clamps facilitates the assembly and servicing process, reducing the time needed for installation and replacement of components.
What is particularly important, PWBS connectors have as many as 12 polarisation options, eliminating the risk of incorrect connection, which is especially important for quick service and maintenance operations. In addition, the product is fully compliant with key railway standards such as EN 45545-2, IEC 60077-1, EN 50124-1, IEC 61373, EN 50467, which guarantees compliance with the highest standards of safety, quality and reliability.
The biggest challenges faced by designers are solved thanks to:
- Safety: touch-proof contact protection, fire resistance (EN45545-2).
- Easy installation: quick bayonet connection system, polarisation (12 variants), simple maintenance.
- Reliability in extreme conditions: corrosion resistance (up to 2000 hours), temperature (-60°C to +180°C), dust, moisture, salt and chemicals.
- Compliance with railway standards: EN45545-2, IEC60077-1, IEC61373 – ensuring that vehicles meet the highest industry standards.
Connectors for railway applications
Summary
By choosing PWBS, we can effectively address all key technical challenges, significantly increasing the safety, reliability and service life of the vehicles we manufacture. Thanks to their robust design, resistance to extreme conditions and intuitive assembly system, these connectors reduce the risk of failure and simplify the servicing process. This is an investment in the durability of power and drive systems, which translates into real savings and greater availability of rolling stock in everyday operation.
