Dowei Electric Medium Voltage Regulator VR

Product catalog summary

General Description:

The medium voltage regulator adheres to international standards such as IEC 60076-21, ANSI/IEEE Std C57.15, and NEMA, and is certified by ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA.
It uses mineral or vegetable oil (FR3) and is free of PCB.
Designed for seismic conditions according to ETGI-1.020, IEEE Std 693, and NCh2369, and follows structural standards like ASTM A325, ANSI/AISC 360, and AWS D1.1.
Capable of high altitude correction up to 5000m as per IEC 60076 & IEEE C57.
Offers a robust, maintenance-free solution for pole-mounted or substation applications.
Regulates line voltages with a range from 10% boost to 10% buck in 32 steps of approximately 5/8% each.
Voltage ratings range from 2400 volts (60 kV BIL) to 34,500 volts (200 kV BIL) for both 60 Hz and 50 Hz systems.

Typical Specification:

The single-phase step medium voltage regulator is available in various configurations with different rated voltages, load currents, and power capacities.
Specifications include dimensions (height, length, width), oil capacity, and weight (untanking and total).
For example, a regulator with a 7.62 kV rated voltage and 95 kV BIL can handle load currents from 50 A to 546 A, with power capacities ranging from 38 kVA to 416 kVA.
Similarly, configurations are available for 13.8 kV, 14.4 kV, 19.92 kV, and 34.5 kV rated voltages, each with specific BIL ratings and corresponding specifications.
