Zig-Zag-N industrial grounding transformer 13.8kV 13.2kV 12.47kV

Zig Zag Grounding Transformer Product Overview

Industrial earthing transformers Product Features

• Iron Core：High quality cold-rolled oriented silicon steel sheets are used, with 45 ° full diagonal joints. The iron yoke is clamped with a through screw, and the core column is tied with fiberglass tape. The surface of the iron core is sprayed with silicone resin adhesive to prevent moisture, tighten and minimize noise. This design ensures the low-loss and stable operation of Zig Zag Grounding Transformer and other industrial earthing transformers.
• Winding：Both the inner and outer windings are made of high-quality copper wires, with a segmented cylindrical structure to enhance interlayer insulation. Vacuum drying technology is used, and the formed windings have good electrical performance, high mechanical strength, and low local discharge capacity. The winding process is optimized for the special working principle of Zig Zag Grounding Transformer, ensuring the product meets the strict operation standards of industrial earthing transformers.
• Structure & Insulation：Epoxy resin is not filled with vacuum casting for dry-type grounding transformers, which has stronger smoke and water resistance compared to non encapsulated products.The oil immersed grounding transformer adopts a fully sealed structure and uses corrugated fins for heat dissipation to eliminate the oil storage tank. The oil tanks are sealed with oil resistant rubber strips to prevent the transformer oil from coming into contact with air. The transformer oil does not come into contact with air, ensuring the insulation performance and service life of the product.Both structural types are applicable to Zig Zag Grounding Transformer, making our industrial earthing transformers have the characteristics of small footprint, beautiful appearance, and maintenance free.

• Protective Device：Oil immersed grounding transformers are equipped with pressure relief valves and gas relays, as well as oil level gauges for easy monitoring of transformer oil levels at any time.The dry-type grounding transformer is equipped with a temperature control device and has remote transmission function, making it convenient to inspect the operating temperature of the product at any time.The complete protection system provides all-round safety guarantee for Zig Zag Grounding Transformer and other industrial earthing transformers in harsh working conditions.

Zig Zag Grounding Transformer Main Technical Parameter

 Note:  Neutral Short time Current I₀=I_G, Neural Zero Sequence Impedance Z₀=Z_phase /3±5% off load tap change switch
Declare Z₀ before producing if not a self-limiter
Z₀ tolerance ≤10%
If a resistor will be connected between the brought out Neutral and ground, choose Z₀ as small as possible, and better make Z₀+R= V_LN/I_G
