Features of SCB Series Dry-Type Transformer

Core Technology and Basic Features
01

Technology Source

It is a non-filled insulation dry-type transformer independently developed and produced by advanced international technology. It abandons the traditional filled design, upgrades the insulation performance and operation stability, and its core technology reaches the leading level in the industry, which can adapt to the harsh requirements of complex power distribution scenarios in various fields.


02

Coil Encapsulation

Adopting epoxy resin full encapsulation process, it has six core advantages: non-flammable, fire-resistant, explosion-proof, maintenance-free, pollution-free and compact size. It does not need additional oil pits, oil tanks and oil drain pipelines, and can be directly installed at the load center, adapting to various complex installation environments, greatly saving floor space, improving on-site fire safety and reliability, and is especially suitable for places with high fire-proof requirements.


03

Performance Advantages

Structure and Process: The scientific and reasonable structural design and precision casting process effectively reduce partial discharge, lower operating noise, improve heat dissipation performance, and at the same time reduce no-load loss and load loss, which is in line with the "dual carbon" energy-saving requirements, and has a significant energy-saving effect compared with products of the same specification under the old standard.


Load Capacity: Under forced air cooling conditions, it can operate stably at 140% of the rated load for a long time, with outstanding overload capacity, which can easily meet the peak load and sudden load requirements in various scenarios, and avoid equipment failures caused by load fluctuations.


04

Intelligent Functions

Equipped with an intelligent temperature control system as standard, it integrates four core functions: fault alarm, over-temperature alarm, over-temperature trip and black start, comprehensively ensuring the safe operation of the equipment and realizing "pre-warning, in-process control and post-recovery". At the same time, it can be connected to a computer through the RS485 serial interface to realize centralized monitoring and remote control. It can be matched with an independently developed intelligent management system to realize real-time collection of operating data, abnormal early warning, energy consumption analysis and other functions, comprehensively improving the intelligence level of power management and realizing the transformation from "post-repair" to "pre-prevention".


05

High-quality Materials and Craftsmanship

Iron Core

Selected imported high-quality cold-rolled silicon steel sheets, adopting a fully inclined joint structure. The core column is bound with F-grade non-woven tape, and the surface of the iron core is sealed with insulating resin paint to effectively prevent moisture and rust, greatly reducing no-load loss, no-load current and iron core noise; the clamps and fasteners are subjected to special surface treatment, taking into account the product appearance and structural stability, and extending the service life of the product.


High-voltage Winding

Adopting epoxy resin + filler vacuum pressure impregnation process, which significantly reduces partial discharge and improves the electrical strength of the coil; the inner and outer walls of the winding are filled with fiberglass mesh plates, which enhances the mechanical integrity of the coil, improves the product's ability to withstand sudden short circuits, and ensures that the winding will never crack, adapting to long-term stable operation under complex working conditions.


Low-voltage Winding

Adopting a foil-type structure design, which completely solves the problem of axial helix angle when winding with wires, ensuring balanced turn-to-turn voltage; the coil is equipped with axial cooling ducts to improve heat dissipation efficiency; DMD epoxy resin pre-impregnated tape is used between winding layers to realize overall curing and shaping, further improving insulation performance and structural stability.


Temperature Control and Air Cooling System

Adopting cross-flow top-blowing cooling fans, which have low noise, high wind pressure and beautiful appearance, effectively improving the overload capacity of the transformer; precise temperature control is realized through an intelligent temperature controller, which real-time monitors the operating temperature of the equipment and automatically adjusts the cooling mode to ensure the safe and reliable operation of the equipment under different loads and environments.


Manufacturing Process

The coils are wound on a high-precision winding machine, and the low-voltage windings adopt a foil-type winding structure. For large-capacity products, ventilation ducts are added; after the winding process is completed, vacuum drying is performed to remove moisture and impurities; the entire casting and curing process is strictly operated in accordance with process standards, with real-time monitoring and dynamic adjustment throughout the process. The precision casting process ensures that the coils are free of bubbles and voids, and the product qualification rate can reach more than 99.8%; relying on the automated production line, the full-process standardized operation from raw material processing to finished product inspection is realized, shortening the production cycle and ensuring product consistency.


06
