Utilizing pure copper winding technology and a dry-cast structure, it is suitable for various industrial power distribution scenarios. This product completely avoids the oil leakage and explosion risks of traditional oil-immersed equipment, making it suitable for harsh environments such as indoor spaces, densely populated factory areas, and photovoltaic power stations. It can be used with Box Type Substations, High And Low Voltage Switchgear , and Electric Power Converters, and is also perfectly compatible with power distribution systems using Combined Photovoltaic Substations . This effectively improves power transmission stability, reduces equipment failure probability and long-term maintenance costs, and provides safe and Reliable Power Supply for industrial production and new energy power generation. This 10KV 1250KVA pure copper dry-type transformer is a core piece of equipment for industrial power distribution. Its core is wound with all-pure copper coils, offering excellent conductivity and lower losses. Compared to conventional aluminum-core equipment, power transmission efficiency is significantly improved, and energy consumption is kept at an industry-low level. The equipment adopts an oil-free dry-type structure, eliminating the need for insulating oil for heat dissipation. It boasts advantages such as flame retardancy, explosion-proof properties, and zero pollution. During operation, there is no leakage or open flame hazard, making its safety far superior to traditional oil-immersed equipment. It is widely used in factories, commercial complexes, rail transit, and photovoltaic power stations, and can work in conjunction with various high and low voltage Power Distribution Equipment . It is suitable for fixed, long-term power supply conditions and is the preferred equipment for modern, safe power distribution systems. Core Product Features 1. Low Energy Consumption from Pure Copper Windings: The equipment uses 100% pure copper coils, resulting in high conductivity and low resistance loss. Long-term operation leads to lower energy consumption, effectively reducing enterprise electricity costs. Simultaneously, the coils have strong anti-oxidation and anti-aging properties, significantly extending the equipment's service life. Practical Maintenance Tips 1. Precise Selection for Suitable Scenarios: This dry-type transformer is suitable for indoor and enclosed power distribution spaces. It is strictly prohibited to use it as a substitute for the outdoor-grade Oil-immersed Transformer . When installed with a Box Type Substation , a reasonable ventilation gap must be reserved to ensure heat dissipation. Frequently Asked Questions (

Buyer questions

FAQ for 1250 kVA 10 kV Dry-Type Transformer Pure Copper

What is 1250 kVA 10 kV Dry-Type Transformer Pure Copper best used for?
This model is specified at 1,250 kVA and 10 kV. It is used where the site load, fault level and environmental conditions match the approved datasheet. Share the load profile, ambient temperature, altitude and grid code and the design can be checked against the application.
What is the typical lead time for 1250 kVA 10 kV Dry-Type Transformer Pure Copper?
Standard distribution units typically ship in 25-40 days after drawing approval. Large power transformers and integrated stations are scheduled by design review, core and winding production, tanking, testing and packing. The exact date is confirmed in the quotation.
Which standards and tests apply to dry-type transformers?
Dry-type units follow GB 1094.1, GB/T 6451 and IEC 60076-11. Routine tests cover winding resistance, ratio, impedance, no-load and load loss, insulation resistance and power-frequency withstand. Partial-discharge and temperature-rise type tests are available.
Can a dry-type transformer be installed outdoors?
A standard cast-resin unit is intended for indoor, well-ventilated rooms. For outdoor use an IP enclosure, anti-condensation heaters and a corrosion class must be specified. In many coastal or dusty sites an oil-immersed or prefabricated station is a better fit.
How do I choose between copper and aluminium windings?
Copper gives higher short-circuit strength and a more compact winding; aluminium can reduce first cost for lightly loaded units. The choice depends on fault level, load profile, loss evaluation and the buyer's specification. Both are available.
