Jiangshan Yulan Transformer Co., Ltd. designs and manufactures neutral grounding reactors for high-voltage power systems. The reactor is connected between the neutral point of a transformer or shunt reactor and ground. It limits single-phase ground fault current, provides system damping, and helps control resonance overvoltage.

Manufactured by Jiangshan Yulan Transformer Co., Ltd., the Oil-Immersed On-Load Tap-Changing Arc Suppression Coil (Petersen coil) serves 6–66 kV distribution networks. It enables adjustable neutral-point compensation by on-load tap changing and automatic control to reduce capacitive earth-fault current. Inquire, order, or request a quote.

Manufactured by Jiangshan Yulan Transformer Co., Ltd., this oil-immersed three-phase core series reactor is used in capacitor bank circuits for reactive power compensation and harmonic filtering. It is connected in series with the capacitor bank. Its fixed inductance limits switching inrush current and, with a selected reactance rate, forms a tuned branch to reduce harmonic amplification and resonance risk.

Jiangshan Yulan Transformer Co., Ltd. supplies oil-immersed three-phase core shunt reactors for high-voltage power transmission systems. These products feature fixed reactance, the ability to absorb capacitive reactive power, and voltage stabilization capabilities; custom designs are also available. We welcome inquiries, orders, and requests for quotations.

Jiangshan Yulan Transformer Co., Ltd. manufactures oil-immersed shunt reactors for high-voltage transmission and distribution systems. The company has produced transformers and reactors since 1999. The BKS/BKD series is a fixed-capacity reactive power absorption device connected in parallel with a bus or transmission line. It absorbs capacitive charging reactive power, limits light-load and no-load overvoltage, and supports voltage distribution along long transmission lines. Single-phase and three-phase designs are available for project-specific requirements.

The Oil-Immersed Magnetically Controlled Reactor (MCR) is manufactured by Jiangshan Yulan Transformer Co., Ltd., a transformer and reactor manufacturer established in 1999 with production capability up to 110kV class. It regulates reactive power continuously by controlling DC excitation current, which changes core saturation and equivalent reactance. The oil-immersed design uses transformer oil for insulation and cooling, making it suitable for high-voltage, large-capacity dynamic reactive power compensation and voltage stabilization.
