Jiangshan Yulan Transformer Co., Ltd. manufactures Three-Phase Oil-Immersed Earthing Transformers for high-voltage transmission and distribution systems. Established in 1999, the company has production capability up to 110 kV class. This transformer uses a zigzag winding and a sealed oil-immersed structure. It provides a neutral point for 6–110 kV three-phase three-wire networks where no natural neutral exists. The neutral point can be connected to an arc suppression coil, a neutral grounding resistor, or protective relays. A station load winding is optional.

Jiangshan Yulan Transformer Co., Ltd. manufactures dry-type arc suppression coils for 6–35 kV distribution networks. The coil is connected between the neutral point of a grounding transformer and earth. It tracks the system capacitive earth-fault current and injects an inductive current to reduce the residual fault current and extinguish the arc. The epoxy-cast design is oil-free and suitable for indoor substations, urban distribution networks, and renewable energy step-up stations where fire safety and low maintenance are required.

Jiangshan Yulan Transformer Co., Ltd. supplies Dry-Type Iron-Core Shunt Reactors for medium- and high-voltage systems. These fixed-capacity, cast-resin, oil-free reactors absorb capacitive reactive power and control light-load voltage rise. They suit cable networks and substations. Custom designs are available. Please inquire, order, or request a quote.

Engineered by Jiangshan Yulan Transformer Co., Ltd., the dry-type filter series reactor serves medium-voltage capacitor banks for reactive power compensation, harmonic mitigation, detuning, and inrush current limitation. It offers fixed inductance, cast-resin insulation, and oil-free construction. Custom-built options are available. Inquire, order, or request a quote.

Jiangshan Yulan Transformer Co., Ltd. manufactures dry-type grounding transformers suitable for 6–35 kV distribution networks. Their zigzag windings provide an artificial neutral point for arc-suppression coils or grounding resistors. As oil-free and flame-retardant units, they are ideally suited for indoor substations.

Jiangshan Yulan Transformer Co., Ltd. offers dry-type magnetically controlled reactors (MCRs) for reactive power compensation in medium-voltage systems. These products feature stepless regulation, low harmonic distortion, and rapid response. We welcome inquiries, orders, and requests for project quotations.
