OIL-IMMERSED STATION SERVICE VOLTAGE TRANSFORMER
The SSVT is a voltage transformer insulated in oil that combines the characteristics ofa voltage transformer with power transformation capability. The SSVT has been designed for voltage up to 362kV and with power capability up to 333kVA.SSVT converts the optimum power directly from high voltage side to medium/low voltage side.The SSVT feature rugged transformer designs incorporating high creepage porcelain insulators and high over-voltage capability with impedance protection to limit fault currents.The SSVT is a line-to-ground connected single-phase transformer that can be used either as an individual unit for supplying single-phase loads, or in a three- phase bank to support larger kVA three- phase loads.
SF6 GAS-INSULATED STATION SERVICE VOLTAGE TRANSFORMER
The SF6 gas-insulated Station Service Voltage Transformer (SSVT) is an innovative high-voltage apparatus integrating voltage transformation and auxiliary power supply functions. It directly converts power from high-voltage systems to medium/low-voltage output, providing a reliable and compact solution for substation auxiliary power supply.
Designed for system voltages up to 500 kV and power ratings up to 333 kVA, the SSVT features advanced SF6 insulation technology, high creepage porcelain insulators, excellent overvoltage withstand capability, and impedance protection for enhanced safety and reliability. Equipped with an SF6 gas density monitoring system, it ensures stable operation under various environmental conditions.
The SSVT can be used as an individual single-phase unit or combined into a three-phase bank to support larger auxiliary power requirements in substations.
COMBINED INSTRUMENT TRANSFORMER
JLD Series Combined Instrument Transformer (CT+VT) is an outdoor oil-immersed single-phase instrument transformer designed for 36-245kV high-voltage power transmission and distribution systems. It integrates current and voltage measurement functions for metering and relay protection. Featuring hermetically sealed design, high accuracy, excellent insulation performance, and flexible output options, JLD provides a reliable and compact solution for modern power systems.
