Medium-Voltage Potential Transformers (10~25 kV)
Widely used internationally in revenue and switchboard applications by engineering, construction, and power companies, CIC Potential Transformers (Voltage Transformers) are the result of over 40 years of manufacturing expertise, combined with technology transferred from Messwandler-Bau (MWB) of Germany.
The primary insulation material for CIC's potential transformers is the Araldite® epoxy resin, known for its reliability. The outdoor models make use of cycloaliphatic epoxy resin, similarly to ensure high-quality insulation.
CIC's potential transformers, including OEM/ODM products, are type-tested and routine-tested by CIC-owned, TAF-accredited Advanced Electricity Laboratory (TAF, or Taiwan Accreditation Foundation, is a member of ILAC and a signatory to the ILAC MRA).
Designed for 24kV 4-way switchgear, this MV potential transformer features a high-voltage elbow-type connector on the primary side and a built-in high-voltage fuse for protection. Exterior coated with a metal conductive mixture for shielding. Secondary side sealed and waterproof. Araldite® epoxy as insulation.
Our model EPF-20SH model potential transformer is widely used for both grounding and non-grounding conditions in larger power distribution and industrial enterprises. Not only has this model passed IEC standards for type tests and routine tests, but thermal testing to -45C. It's high reliability and outstanding security makes it a favorite model for distributors to sell in many global markets.
Our model EPF-20SE model potential transformer is widely used for both grounding and non-grounding conditions in larger power distribution and industrial enterprises. Not only has this model passed IEC standards for type tests and routine tests, but thermal testing to -45C. It's high reliability and outstanding security makes it a favorite model for distributors to sell in many global markets.
Our model EPF-20SI model potential transformer is a single-phase epoxy resin casting with fully enclosed construction. Designed to carry 50Hz or 60Hz frequency for 12-24KV equipment. The burden range of this model can extend to 1000VA, and it can be used to measure and monitor different voltage systems.
These outdoodr, pole-mounted potential transformers, designed for billing purposes, are made with a special blend of epoxy material which is able to withstand the sun's UV radiation. These potential transformers have been designed for difficult outdoor and environmental elements such as salt, moisture, ultraviolet radiation, strong winds and other factors. The VPF-15/24 Series Potential Transformers have been supplied to utility companies for many years, and they have earned an excellent reputation. These products provide a burden of 25VA and an accuracy level of Class 0.2s, 0.2 and 0.3. Suitable for voltage systems of 12KV to 24KV, these potential transformers have performed well in partial discharge tests, which signifies the longevity and durability of these products.
Our EPF-20SFL potential transformer is designed to be used with a GIS switchgear panel. From the top of the primary high voltage terminal to the bushing end - which are surrounded by black rubber, SF6 gas insulation is used, while other components are used without the need of the SF6 gas in normal surroundings. The new design simplifies the set up process of the GIS switchgear panel, as well as diminishing the SF6 gas usage, which in turn allows for the GIS panel size to be more compact. The sophisticated design is a tribute to our R&D department.
