The hermetic Transformer Protection Relay MCHD for hermetically sealed, liquid immersed distribution transformers without gaseous cushion in accordance with EN 50216-3. Each Hermetic-protection relay MCHD is individually tested for tightness and proper functioning.

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.

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".

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.

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 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.

The coolers in general are used for specific types of transformers, such as furnace transformers or rectifier transformers. A further application is machine transformer cooling at hydraulic power plants. Transformer oil water coolers are available in different design versions.

The DC-voltage converters developed for the electronic components in the motor car are characterised by their ease of installation in every vehicle. The high degree of stability, the compact design, sustained short-circuit resistance as well as the high level of operating safety are the quality hallmarks of this series. The areas of application span the mobile employment of 12-V-consumers in vehicles with a 24-V-onboard network. The devices are particularly suitable for operating car radios, stereo units, radios, cooler units, car telephones, computers, 12-V-trailer lighting etc. The voltage converter converts an input direct voltage into an output direct voltage. The input voltage must be greater than the output voltage. No base load is required at the output end. A 26 kHz PWM switching controller is used for this purpose. Input and output are not isolated. The common earth is connected with the voltage converter housing.

INGENERIC beamPROP The INGENERIC beamPROP is a lens array which matches the beam parameter product (BPP) of the fast and slow axis of high power diode laser arrays. The beamPROP is a key component for the fiber coupling of diode bars dense wavelength beam combining. Both applications make high demands on the components, which are met by INGENERIC’s outstanding manufacturing technology, guaranteeing highest levels of efficiency for diode lasers. Achieve the highest beam quality through the four major features behind the beamPROP: complete utilization of the aperture by minimized transition zones minimum aberrations achieved by highest level of precision and uniformity of single lenslets an exact rotation of the emitter is achieved through the defined center thickness accuracy minimum pointing errors due to an exact position of front and back surfaces

Achieve the highest beam quality through the four major features behind the beamPROP: - complete utilization of the aperture by minimized transition zones - minimum aberrations achieved by highest level of precision and uniformity of single lenslets - an exact rotation of the emitter is achieved through the defined center thickness accuracy - minimum pointing errors due to an exact position of front and back surfaces

Funnels for pipes and bright steel In the production of pipes and bright steel socalled funnels are used for threading in the production plants. In most cases funnels made of polyamide are used, but due to the material hardness and the sharpedged pipe ends wear out very quickly. It depends on the material sphere As an alternative, secutex offers polyurethane funnels for this purpose. In contrast to polyamide, these are softer from the material and therefore also more wearresistant than sharpedged pipe ends. This means longer service life for the customer as well as better surface protection for very sensitive materials. For every size secutex funnels can be produced in the required dimensions according to customer drawings.

Wipers for steel bars In the production of pipes and steel bars, socalled wipers are used for cleaning. The wipers have a round or rectangular outer profile and an inner profile that matches the shape of the object to be cleaned. Normally, several wipers are mounted in series, whereby the passthrough openings are smaller than the profile. The bar is pushed through the elastomer plates at high velocity, and the rubbery material strips the surface free from grease and cleaning fluid residues. It is the edge that counts! Just a like a car window wiper, it is the edge that counts. Normally, the wipers are stamped from sheet goods. During stamping, the elastomer becomes distorted; the inner edge is therefore not dimensionally stable and is at an angle. Only part of the edge wipes emulsions from the surfaces depends on the profiles. This edge is rapidly worn down; the cleaning action is then unsatisfactory. Streakfree cleaning
