S11/13/20/22 Oil-immersed transformers

Overview

The S11/13/20/22-M (20-10KV) series of double-winding, off-circuit voltage-regulating, fully sealed, oil-filled power transformers are three-phase, oil-filled distribution transformers manufactured by our company. They utilize a novel insulation structure for improved short-circuit resistance; the core is constructed from high-quality cold-rolled silicon steel sheets; the high-voltage windings are constructed from high-quality oxygen-free copper wire and employ a multi-layer cylindrical structure; all fasteners feature a special anti-loosening treatment. These high-efficiency, low-loss products can significantly reduce power consumption and operating costs, resulting in significant social benefits. They are a nationally recognized high-tech product.

Product Specifications

High-Quality Materials

Using oxygen-free copper wire with a lower anode current and undergoing a series of additional surface treatments for a smoother, burr-free design, this reduces transformer load losses and ensures more reliable electrical performance.

Using high-quality silicon steel sheets, with improved performance, we use silicon steel sheets with even lower unit losses, resulting in even lower no-load losses.

Using high-quality laminated wood insulation, this material resists cracking and remains intact even under short-circuit currents.

Using deep-filtered transformer oil, this material reduces moisture, gas, and impurity levels, ensuring more reliable transformer operation.

Using high-quality rubber sealing materials, this material effectively resists aging and prevents leakage.

All raw materials undergo rigorous quality inspection, and the outsourced suppliers of key components are ISO9001 certified.

Main technical parameters

Based on traditional structures and proven technologies, our company has made numerous improvements. These include a spiral coil with longitudinal oil channels for improved internal heat dissipation.

Improved effective support for the coil ends enhances short-circuit current resistance.

A new lifting and body positioning structure ensures greater reliability during long-distance transportation and operation. We also offer many unique and reliable structures to serve you.

Using higher-performance transformers will provide even higher levels of technical content.
