Product Description

RELIABLE STRUCTURE
Special training of external construction

Reliable structure our company has made many improvements based on the traditional structure and mature technology

---Spiral coil with longitudinal oil duct for better internal heat dissipation

---Improved coil end face effective support, anti-short-circuit current ability is stronger!

---New hoisting structure and body positioning structure are adopted to ensure more reliability in long-distance transportation and operation.

--We also have many unique and reliable structures to serve you;

---The use of a higher level of performance transformer, will have a higher level of technical content.

Quality materials

---Selection of lower resistivity oxygen-free copper wire, and after a series of additional surface treatment, more smooth, no burr sharp angle, so that change

---The load loss of the transformer is lower and the electrical performance is more reliable.

---Selection of high-quality silicon steel sheet, with the improvement of performance level, the silicon steel sheet with lower unit loss is adopted to make the transformer no-load loss lower.

---Selection of high-quality laminated wood insulation, never cracking, even under the action of short-circuit current, also motionless.

---Selection of transformer oil after deep filtration, lower water, gas, impurity level, transformer work more reliable.

---Selection of high-quality rubber sealing materials, effective anti-aging, eliminate leakage.

---All raw materials are subject to strict quality inspection, important parts of the outsourcing units have passed ISO 9001 quality assurance system certification.

Good technical and economic performance

S 11 series products in the s 9 series technology, the average no-load loss reduced by 31% ; no-load current than s 9 decreased by 75-90%;

The average temperature rise is reduced by 10k, the service life of the product is more than doubled, and it can run for a long time even under the condition of 20% overload.
Product operating noise reduced by an average of 3-5 decibels.

Fully sealed (M )

Compared with the ordinary oil-immersed transformer, the full-sealed distribution transformer cancels the oil storage tank, and the wave fin of the oil tank replaces the oil pipe as the cooling element. Corrugated oil tank is made of high-quality cold-rolled sheet in a special production line; the wave fin can expand and contract with the volume of transformer oil, so that the transformer is isolated from the atmosphere, prevent and slow down oil deterioration and insulation dampness, enhance operation reliability, normal operation and maintenance-free. The surface of corrugated oil tank is coated with three anti-paint after degreasing, rust removing and phosphating, which is suitable for use in metallurgy, petrochemical, mine and other environments.
