3. Core Product Features & Advantages
This 125KVA 11KV dry type distribution transformer adopts advanced vacuum high-temperature casting technology, with superior structural design and material configuration, covering safety, durability, energy saving and environmental protection advantages:
-
High-Strength All-Copper Coil Structure: Both HV and LV coils adopt full copper conductors reinforced by glass fiber. After high vacuum drying and epoxy resin integral casting and curing, the coils form an integrated firm cylinder structure. It boasts excellent mechanical strength, strong short-circuit resistance, extremely low partial discharge, high operational reliability and ultra-long service life, effectively avoiding coil deformation and damage caused by sudden current impact.
-
Flameproof, Explosion-Proof & Zero Pollution: Equipped with imported composite insulation materials of epoxy resin and glass fiber, and doped with high-efficiency silicon powder. Compared with traditional glass fiber epoxy transformers, it has greatly improved thermal conductivity and flame retardancy. No toxic gas or harmful substances are released under high-temperature operation, achieving environmental-friendly and safe operation with no pollution.
-
Moisture-Proof & Severe Environment Adaptability: The cast coil structure completely prevents moisture absorption, avoiding insulation failure caused by humid environment. The iron core clamp is coated with special anti-corrosion coating, which can operate stably in humid, dusty and other severe working conditions. No regular moisture removal treatment is required for intermittent operation, reducing daily maintenance workload.
-
Strong Overload & Impact Resistance: Optimized internal structure design endows the transformer with excellent short-circuit resistance and high lightning impulse resistance, effectively resisting grid voltage fluctuation and sudden short-circuit faults. The optional fan cooling (AF) system can significantly improve short-time overload capacity and ensure stable and safe operation under peak load.
-
Efficient Heat Dissipation & Low Energy Consumption: The coil surface is coated with thin-layer high-heat-conduction resin, which accelerates heat dissipation. The standard natural air cooling (AN) mode meets daily operation needs, with low no-load loss and load loss. It features low operating noise, significant power-saving effect and economical long-term operation.
-
Small Size & Low Installation Cost: Compact overall structure, small volume, light weight and small floor area. Unlike oil-immersed transformers, it does not need oil storage pools, fireproof partition walls and special fire-fighting facilities, saving civil engineering investment and site cost.
-
High Safety & Flexible Installation: Zero fire and explosion risk, eliminating potential safety hazards of oil leakage and combustion. It can be installed centrally in distribution rooms or dispersedly near load centers and power consumption points, effectively reducing low-voltage wiring distance, lowering cable engineering cost and improving power supply efficiency.
-
Maintenance-Free Operation: Stable material performance and integrated sealing structure avoid daily oil replacement, cleaning and other maintenance work, greatly reducing later operation and maintenance costs.

5. Frequently Asked Questions (FAQ)
Q1: What voltage levels does this 125KVA dry transformer support?
This SCB-125/10 dry type transformer supports three mainstream high voltage levels: 10KV, 10.5KV and 11KV, with a fixed low voltage output of 0.4KV, fully matching conventional industrial and civil 11KV distribution power system standards.
Q2: What is the difference between AN and AF cooling modes?
AN refers to natural air cooling, which relies on natural air convection for heat dissipation, suitable for conventional continuous rated load operation, no extra energy consumption and low noise. AF is fan forced air cooling, which is equipped with auxiliary cooling fans. It can improve the short-time overload capacity of the transformer, suitable for scenarios with occasional peak load and high continuous operation load requirements.
Q3: Can this 11KV dry transformer work in humid and dusty environments?
Yes. The epoxy resin cast coil is completely insulated and moisture-proof with no moisture absorption risk. The core clamp adopts special anti-corrosion coating, enabling stable operation in humid, dusty and other severe industrial environments. No regular moisture removal maintenance is needed during intermittent use.
Q4: Is this dry type transformer fireproof and explosion-proof?
Absolutely. It adopts imported flame-retardant epoxy resin and glass fiber composite materials with silicon powder added for enhanced flame retardancy. No flammable oil is used, no toxic or harmful gas is generated at high temperature, with zero fire and explosion risk, meeting high-standard safety requirements for indoor and dense equipment installation.
Q5: Does the 125KVA dry transformer require daily maintenance?
This product is designed for maintenance-free operation. It has no oil leakage, aging and replacement problems of oil-immersed transformers, with stable structural and material performance. Daily routine inspection is sufficient, which greatly reduces later operation and maintenance time and cost.
Q6: Where can this 11KV dry power transformer be installed?
Due to its high safety performance, it has no special restrictions on installation scenarios. It can be installed in indoor distribution rooms, factory workshops, commercial buildings, and can also be deployed near load centers and power consumption points in a decentralized manner to shorten wiring distance and save installation costs.
Q7: What are the core advantages of full copper coil dry transformer?
Full copper conductor has better electrical conductivity, lower power loss and more stable heat dissipation performance compared with aluminum coils. It features stronger short-circuit resistance, lower operating temperature rise, longer service life and more economical long-term operation, which is the preferred configuration for high-standard industrial power distribution.
