Product Description

Company profile
Weifang Quneng Electric Technology Co., Ltd., established in March 2017, is located at No. 1277 Yudong Road, Dongcheng Street, Linqu County, Weifang City, Shandong Province. It is a new industrial company specializing in electrical and electrical equipment installation engineering, industrial automation engineering, system integration, maintenance, and sales of electronic and electrical equipment.The company has an advanced technical level, and dozens of senior engineers, particularly electricians, and welders. The company has obtained a four-level installation (repair, test) power facility license, construction enterprise qualification certificate, safety production license, high-tech enterprise, multiple credit rating certificates, GGD, GGJ, MNS, PZ, XL type, JP, and other low-voltage power distribution products, and passed the CQC product certification of China Quality Certification Center.The company's main products are high-voltage switchgear: KYN61, KYN28A-12, XGN2-12, HXGN, GKG (KA) mining cabinets, switching stations, etc.; low-voltage switchgear: MNS, GCS, GGD, PZ, XL type, intelligent power distribution unit (JP series), high-frequency DC power supply cabinet; JYDXH series arc suppression and harmonic elimination cabinet; VS1 vacuum circuit breaker, etc.; substation. The products are sold to all regions of the country and are widely used in power grids, petrochemicals, steel, mining, power generation, biological engineering, large-scale construction projects, and other fields.
High voltage: 10 (6, 6.3, 10, 10.5, 11) Low voltage: 0.4kVConnection Group: Y.yno or D.yn11 Voltage regulation range: ±5% or ±2×2.5%

S11 belongs to the fully sealed distribution transformer with a rolled iron core. It is a new generation of low-noise and low-loss transformers developed in recent years. Its iron core has no joints, which greatly reduces the no-load loss and no-load current, making the no-load carrying current reduced by 60% to 80%. The high and low-voltage coils are wound continuously on the core column, the windings are tight and the concentricity is good, which further enhances the anti-theft performance of the product. Noise drops by more than 10 decibels. The temperature rise is 1620K lower. Due to the continuous winding of the iron core (with a pure circular cross-section), the orientation of the silicon steel sheet is fully utilized, reducing the no-load loss by 20% to 30%. The low-voltage winding with a capacity of 630"25.0KVA adopts a cylindrical or spiral structure, with high mechanical strength, balanced ampere-turn distribution, and good short-circuit resistance. Displacement occurs, and at the same time, all fasteners are equipped with fastening nuts to ensure that the fasteners will not loosen during the long-term operation of the product, which meets the requirements of not hanging the core.

The transformer adopts a corrugated oil tank, and the oil storage tank is canceled. The tank cover and the tank edge are completely welded or fastened with bolts, which prolongs the service life of the transformer oil.After degreasing, derusting, and phosphating treatment, the surface of the product is sprayed with primer and topcoat, which can meet the special requirements of metallurgy, petrochemical systems, and humid and polluted areas. The selected components adopt a fully sealed transformer oil tank and are equipped with a pressure relief valve and a signal thermometer as required by the standard. Gas relay, etc., to ensure the safe operation of the transformer. This series of products has a beautiful appearance and small size, which can reduce the installation area, and is an ideal maintenance-free high-quality product.
