Medium-Voltage Potential Transformers (3~7.2 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).
Indoor medium-voltage single-phase coil molded potential transformers for power systems ≦ 7.2 kV. Laminated-core & cut-core models. 2 primary-side fuses. Circuit breaker operation power source (EP-6SFK).
Mounted on switchgear (3.3/6.6 kV) as an auxiliary power source for circuit breaker operation. Insulated with Araldite® epoxy resin, these potential transformers also feature a Class-F heat-resistant insulation material for the coils. Two fuses on the primary side offer protection against overload and short circuit currents.
Indoor grounding potential transformer with a fuse on each of the 3 phases on the primary side. Used with measuring or monitoring instruments, or for ground-fault protection. 5-legged laminated core. Coils insulated with Araldite® epoxy resin.
