FAQ

1. Ultra-Low Line Loss: Low-voltage design of 2×0.23kV reduces low-voltage current to 1/2 of ordinary transformers; line loss is 1/4 (P=I²R), saving 75% energy for long-distance power supply. Keywords: low line-loss single-phase transformer, energy-saving rural transformer

2. Flexible Installation: Can be mounted on platforms or utility poles, eliminating the need for large foundations, reducing installation costs by 40% and saving space. Keywords: pole-mounted transformer, space-saving oil-immersed equipment

3. High Material Quality: Core made of high-grade cold-rolled silicon steel sheets minimizes no-load loss (36W-232W); windings use oxygen-free copper for low resistance and stable conductivity. Keywords: cold-rolled silicon steel core, oxygen-free copper windings

4. Wide Voltage Adaptability: Supports high-voltage tap ranges of ±2×2.5%/±5%, adapting to voltage fluctuations in remote areas (10% voltage deviation acceptable). Keywords: voltage-adaptive transformer, remote area power supply

5. National Certification: Passed type tests by the National Transformer Quality Supervision and Testing Center, ensuring compliance with GB/T 6451-2015 standards. Keywords: certified single-phase transformer, GB/T 6451 compliance

1. Rural Agricultural Production: Powers irrigation pumps, grain drying equipment, and greenhouses, with low line loss adapting to long-distance rural power lines.

2. Remote Mountainous Area Lighting: Supplies electricity to mountain villages and border posts, supporting pole-mounted installation in rugged terrain.

3. Urban Grid Energy-Saving Transformation: Replaces old transformers in residential communities, reducing line loss and improving power supply stability for households.

4. Small-Scale Commercial Use: Powers convenience stores, rural clinics, and small workshops, with compact design fitting limited installation space.

1. Q: Why is the low-voltage 2×0.23kV instead of 0.4kV?

A: 2×0.23kV reduces current by half, cutting line loss to 1/4—ideal for long-distance power supply in rural areas.

2. Q: Can it be used in areas with frequent voltage fluctuations?

A: Yes, the ±2×2.5% tap range adjusts voltage to stabilize output, adapting to ±10% fluctuations.

3. Q: What is the service life of this transformer?

A: Under normal maintenance, the service life is 15-20 years, with the oil tank and windings having anti-corrosion treatment.
