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.

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.

With securoll secutex offers a specially developed coating for cylinders and rolls, which is cast in form or applied directly onto the roller core. During product development the vast experience of secutex with all types of coatings was introduced. secutex supplies a wide selection of securoll for almost any application.

These compact half-wave and bridge rectifiers are ideal for installation in space restricted junction boxes of brake motors. They can be delivered with flying leads or terminals for connection. Various accessories are available to meet different installation requirements.

Thanks to extremely compact design the overexcitation rectifier "Slim Collection" can be installed in very restricted space. The module features a central bore for screw fixing inside the terminal box. It can also be installed by using an adhesive pad.

The compact collection is available as bridge, and half-wave rectifiers in two voltage variants. Two different housing variants allow mounting by screwing or snapping in.

The Regular Collection is available as bridge, half-wave, and bridge/half-wave rectifiers. The bridge/half-wave rectifiers reduce the output voltage after the brake is released. Depending on the selected rated coil voltage of the brake, either a faster switching by overexcitation, a reduction of the electrical power while the brake is released or a combination of both is possible.

These half-wave and bridge rectifiers are ideal for installation in the junction boxes of medium-power brake motors, brakes and solenoids. Accessories include flying leads and a range of mounting hardware so that installation on DIN rails is also possible. Encapsulated versions for an extended operating temperature range are available as options. In case of additional DC side fast turn-off, the induction voltage generated by inductive loads is limited within the rectifier.

The rectifier with built-in current sensor for fast turn-off is designed for the operation of electromagnetic devices. It ensures fast turn-on and turn-off. The rectifier with bridge circuit comprises a thyristor and timer. During overexcitation, the rectifier delivers bridge rectified output voltage before changing over to half-wave rectification. On the DC side, the output voltage is enabled by the built-in current sensor which measures the AC current of the connected motor. If the motor is stopped, the rectifier turns off on the DC side as soon as the current falls below the turn-off threshold. The turn-off voltage generated by the inductive load is limited. The rectifier is suitable for connection in parallel with AC motors. The current sensor must be wired into the motor current path in such a way that the current flow created when the motor operates in generator mode will not pass through the sensor. This is crucial to avoid delayed or impaired DC side switching.

These overexcitation rectifiers are designed to increase the attractive force and reduce the attraction time of actuating solenoids, to shorten the coupling and disconnection times of clutches and brakes and to decrease the power consumption of clutches, brakes and actuating solenoids. To increase the attractive force, the solenoid is overexcited during the overexcitation time, applying bridge rectified voltage. Then the rectifier changes over to the selected holding voltage which must not exceed the rated voltage of the solenoid.

ESM for AC-brakes: The module consists of a time-controlled rectifier with integral electronic fast turn-off. During start-up, the ESM delivers bridge-rectified output voltage before changing over to half-wave rectification. The built-in voltage sensor ensures that the DC side output voltage is interrupted electronically when AC input voltage is removed. Thanks to its compact design, the ESM can be installed in very restricted space. ESM for DC-brakes: The module keeps the voltage supplied to the electromagnetic device at a constant level over a wide input voltage and temperature range. Full operating voltage is applied to ensure fast switching when the load is switched on. The module then reduces the power supply to constant holding voltage. A 30% reduction provides power savings of 50%. The ESM is very compact thanks to the use of state-of-the-art microelectronic and power electronic components. Overexcitation time and holding voltage can be factory-programmed to customer demands.
