Our radiator valves DIN 42560 type A and type A OR are designed to be welded onto the transformer wall or on connection pipes. The radiator will be flanged on the four M16 holes (PCD=160 mm). The housing of the radiator valve is made of forged steel S355J2G3 and thus not subject to any leakage as it may occur with casted housing. Due to the metal sealed clap a low leakage is permitted while the soft-sealed radiator valve is absolutely oil- and vacuum-tight. Both types are absolutely tight in operation condition to the outside. Our welding neck radiator valves DIN 42560 type A NW 80 fulfil the tightness requirements and operating conditions in accordance with DIN 42560 as well as EN 50216-8.

Our radiator valves DIN 42560 type B and type B OR for transformers are designed to be mounted between two flanges or between tank wall flange and radiator flange. The flange is made of forged steel S355J2G3 and thus not subject to any leakage. Flange thickness is h=40 mm with recessed body. Our radiator valves DIN 42560 B and B OR NW 80 fulfill the tightness requirements and operating conditions in accordance with DIN 42560 as well as EN 50216-8. Due to the metal sealed clap a low leakage is permitted while the soft-sealed radiator valve is absolutely oil and vacuum-tight (zero-leakage). Both variations are absolutely tight in operation condition to the outside of the transformer.

The Buchholz Relay MBP in accordance with EN 50216-2 protects liquid immersed transformers and reactors with conservator. It will be mounted in the pipeline between transformer and conservator tank. The Buchholz Relay MBP operates as a protection device that can be provided with either two contacts or four contacts for alarm and tripping. Each Buchholzrelay is individually tested in a test facility for tightness and proper functioning.

Dehydrating breathers are being used for liquid immersed transformers in order to protect the insulating liquid and prevent the harmful moisture absorption from ambient air, which occurs when the load on the transformer fluctuates.The dehydrating breather removes practically all moisture from the air that flows through it into the conservator when the transformer is cooling down. This largely prevents any reduction of the dielectric strength and the formation of condensation in the expansion tank. Thus, the dehydrating breathers increases the operational safety of transformers.

The oil drain device Type C2 is used for oil sampling or emptying the transformer tank. The device is welded into the transformer case. The device is designed for use together with connection pipe F DIN 42551 for draining the transformer case for regeneration purpose of the oil. The oil drain device Type C2 is deisgned in accordance with EN 50216-4:2002 type C2.

The magnetic oil level indicator 1 225 with vertical float movement is used for hermetically sealed transformers. The float movement is transmitted to the display by means of a magnetic clutch. This ensures that, in case of damage to the dome, no oil leakge of the transformer occures. The body is made of brass. The thread connection of the oil level indicator 1 225 is 1 ½".

Pressure relief devices for liquid-immersed transformers open in case of an internal fault and guarantee that the occured overpressure can properly release. Pressure relief devices close with decreasing pressure back to completely closed and leaktight position. Pressure relief devices for transformers can be installed in any position or inclination on the cover or the wall of a transformer. Upon request a transformer can be equipped with several pressure relief valves.
