HV Voltage transformer for measuring and/or protecting up to 52 kV, used for measurement instruments, meters, relays and other similar devices. Designed to be used outdoors.
The transformer VFP-52 is a phase-to-earth transformer; that is, a single-phase transformer, used to keep one of the ends of the primary winding directly connected to earth.
The transformer has been designed to withstand high G levels due to earthquakes. It disposes of an expansion tank to compensate oil volume variations. There is also, in the upper end, a level indicator to show if the transformer and the insulating oil are in their usual working conditions.
The internal insulation is composed of paper-oil and external insulator is made of porcelain, with a creepage distance in compliance up to 35mm/kV regarding the polution level.
Manufactured in accordance with IEC 61869:1 & IEC 61869:3 standards. Other standards or specifications under consultation.
HV Voltage transformer for measuring and/or protecting up to 24 or 36 kV, used for measurement instruments, meters, relays and other similar devices. Designed to be used outdoors.
The primary winding is protected by insulation type E cycloaliphatic resin (in accordance with IEC 60085 standard); the core and secondary(ies) are outside the bushing. This type of resin is specifically used for devices installed outdoors, and resists the combined action of the weather and the electrical field.
The transformer VKEF-24/36 is a phase-to-earth transformer; that is, a single-phase transformer, used to keep one of the ends of the primary winding directly connected to earth.
The range of VKEF transformers has been designed taking into account the environment – no fluoridated oil or gas have been used as insulation material.
It is mechanically resistant and damp-proof, oil-proof, dust-proof and resists most chemical products.
Manufactured in accorance with IEC 61869:1 & IEC 61869:3 standards.
HV Voltage transformer for measuring and/or protecting up to 36 kV, to be used in HV cells gas insulated.
This model VKE-36 allows a primary connection through a plug designed according to UNE-EN 50181.
The transformer is shielded by means a metallic enclosure that covers the resin body and allows it installation without any distance between them because the surface of the device is earthed and allows a better space optimization.
The transformers can be supplied unshielded on request for their installation in open cells, always taking into account the safety distances between them.
The primary winding is occluded in class E epoxy resin, the magnetic circuit and the secondary winding are outside the resin enclosure.Because of this construction there is no risk of projection of fragments.
Possibility of installation in any position. Manufactured in accordance with IEC 61869:1 and IEC 61869:3 standards.
HV Voltage transformer for measuring and/or protecting up to 36 kV, used for measurement instruments, meters, relays and other similar devices. Designed to be used indoors.
The VCJ-36 is a phase-to-phase transformer, that is, a two phase or two poles transformer. In order to guarantee its dielectric level, it is filled with SF6 gas.
This transformer can be anti explosive or not, depending on customer requirements.
The anti explosive version disposes of a high quality safety valve. The function of this valve is to eliminate internal overpressures that can appear due to long term defects, in the way to avoid violent projections of fragments.
It is mechanically resistant and damp-proof, oil-proof, dust-proof and resists most chemical products.
Possibility of installation in any position.
Manufactured in accordance with IEC 61869:1 and IEC 61869:3 standards.
Bushings with built-in conductor for various applications in the production and distribution of electricity.
The conductor, in aluminium or brass, is coated with epoxy resin casting under vacuum forming a rigid body with excellent dielectric, thermal and mechanical properties. This body is located within a porcelain insulator that provides creepage distance and excellent weather resistance.
Laboratorio Electrotécnico designs and manufactures different models of bushings according to the need of its customers. Indoor and outdoor service, up to 36 kV and 5000 A.
The load resistors cabinet ARM consists of a resistance box, a non-sealable terminal strip and a 2A circuit breaker, located in a metal cabinet with ventilation and connections protected by a sealable cover to prevent tampering.
Box load resistors, is comprised of three load resistors contained in a metal box with surface treatment to prevent corrosion and to evacuate the heat.
It is designed for indoor use. On request it can be manufactured for outdoor service and with different configurations.
Its function is to consume the necessary power for the transformer to work at least at 25% of the accuracy burden in cases where the loads connected to the unit (meters, relays,etc.) do not reach the minimum necessary to guaranteed measurement accuracy.
