Best-in-class cast resin transformers are engineered to maximize your investment through reliable performance and a long service life. More Information INSTALLATION, USE AND MAINTENANCE MANUAL ENG 4 Power Sp.zo.o. –Ul. Józefowska 6, 40-144 Katowice, Polska 2.0 - REFERENCE STANDARDS The cast resin transformer has been designed and manufactured by Power. Cast resin type transformers are an exception. Because of their construction, the materials in cast resin type transformers can be difficult and uneconomical to recycle. When a cast coil fails, the entire winding, encapsulated in epoxy resin, is rendered useless and typically ends up in a landfill. Specification Cast Resin Transformers LS CAST RESIN Transformers are normally available with specification as follows: Rated voltage HV COIL : up to 36kV LV COIL : up to 600V * Dual voltage coils can also be supplied. Standard Tapping range : ±2.5%, ±5% * Other ratings are available by request Power capacity Single phase : 20 ~ 2,000kVA
resin. Used in commercial construction and industrial application. VPE—Vacuum Pressure Encapsulated with silicon resin. Applied where MIL-1-24092 spec is required (salt-spray application). Cast Coil—Uses the electrical and mechanical strength of epoxy to provide higher levels of performance and environmental protection in high moisture ... This Technical Specification concerns the design, manufacture, conformity tests, delivery to CERN and documentation of five cast-resin rectifier power transformers, rated 18 kV/900 V, 4.8 MVA and three pre-magnetising transformers. The power transformers will feed 6-pulse rectifier thyristor bridges in DC power converters. Dry type transformer Oil immersed transformer Mining flame proof substation Integrated substation Phase-shift Rectifier transformer Reactor Special transformer Cast resin transformer Max. capacity 30mva, 35kv, Customized solutions for various applications,Fire Resistant,Higher Short-circuit Strength Cast Resin transformers are supplied either in IP00 specification or in sheet steel ventilated enclosures complete with HV and LV cable boxes. Cast Resin Transformers are Hazard free to the environment, extremely reliable and suitable for places where environmental issues and fire safety are major important factors.
Trihal is a three-phase dry type transformer cast under vacuum in epoxy resin with an active filler. It is this active filler, essentially composed of trihydrated alumina, which is the origin of the Trihal trademark. The magnetic core is made from laminations of grain oriented silicone steel ...

More Information HV/LV distribution transformers TRIHAL cast resin dry type transformers 160 to 3150 kVA insulation level 24 kV - low voltage 400 to 433 V - 50 Hz thermal class F - ambient 40° C, altitude 1000 m France Transfo insulation level: 17.5 kV and 24 kV - low voltage 400 V to 433 V insulation level: 7.2 kV and 12 kV - low voltage 400 V to 433 V rated power (kVA) CAST RESIN TRANSFORMERS SELECTION CRITERIA 5 Legrand is one of the most important producers of cast resin transformers. Thanks to a long experience in the production of cast resin transformers up to 36 kV and constant investment in R&D, Legrand is capable to grant high quality products, with excellent performance in many and varied applications.
Outer insulation will be with vacuum mixed, homogenous Resin casting. Minimum 2 mm thickness of resin above the coil of the CT will be provided. SECONDARY TERMINAL: A three core (2.5mm) PVC insulated flexible multi strand copper wire lead will come out directly from the CT as secondary terminal. Two wires will be used for CT incoming & outgoing. Normally conventional distribution and power transformers are of oil type i.e. the tank of the transformer is filled with oil which acts as a cooling medium for the winding. These transformers meet strict parameters with respect to electrical system demands and functioning in areas with extreme climatic conditions. ABB's dry and cast transformers are virtually maintenance free and are manufactured in accordance with industry and international standards including ISO 9001.
