1000 kVA Three Phase Oil Power Distribution Transformer

The S13/22-M 1000 kVA Three Phase Oil Power Distribution Transformer is a flagship medium-capacity product of Jinhand Electrical, a leading manufacturer and direct factory supplier of electrical equipment in China, exclusively engineered for 50Hz/10kV standard industrial power systems.

Advantages

1.Fully Sealed Structural Design：The transformer adopts an integrated fully sealed structure. All flanges, terminals and joints are sealed with high-temperature and oil-resistant materials, isolating internal oil, core and windings from outside air.
2. Low Maintenance & High Durability：This design prevents oil aging, moisture emulsification and internal dust accumulation. It greatly improves equipment durability and reduces daily maintenance by more than 90% vs. traditional open-type transformers.
3. Optimized for ≤10kV Power Systems：The product is specially designed for ≤10kV power systems, with strong adaptability to industrial and distribution scenarios.

MAIN TECHNICAL PARAMETERS

Production Process Advantages

1.Advanced Manufacturing and Precision Processing Technology：High-precision lamination and vacuum annealingAdopt CNC shearing and folding machine for precision cutting, step-by-step lamination process to ensure the uniformity of the magnetic circuit; the core is subjected to vacuum annealing treatment to eliminate internal stress, reduce iron loss by 15% and improve magnetic conductivity significantly.
2.Strict and Comprehensive Full-Process Quality Control System：In accordance with ISO9001 quality management system standards, Jinhand Electrical has established a full-process quality control system covering raw material procurement, production processing, product assembly and finished product testing for the S13/22-M 1000 kVA transformer, with 18 quality inspection links and 4 full-inspection nodes, ensuring a factory qualification rate of 100%.
3.Key Core Technology Advantages：The R&D team has independent intellectual property rights for the electromagnetic design of medium-capacity transformers, using finite element simulation analysis software to optimize the core and three-phase winding layout, realizing the optimal matching of loss, volume and noise, and ensuring the high efficiency and low noise operation of the 1000 kVA model.

Green Energy-Saving Characteristics

1.Ultra-Low Loss Energy-Saving Design, Exceeding International Energy Efficiency Standards：Low-loss core design: Adopt 30Q120 high-grade cold-rolled oriented silicon steel sheets with ultra-low iron loss 1.2W/kgat1.7T,50Hz, which is 30% lower than ordinary silicon steel sheets in iron loss, effectively reducing the no-load loss of the transformer.
2.Environmentally Friendly and Non-Toxic Materials, Complying with International Environmental Standards：All insulating materials comply with the EU RoHS directive, free of lead, mercury, cadmium and other heavy metals, and non-toxic and harmless during production, use and disposal, avoiding environmental pollution.
3.Low-Carbon Operation and Green Production, Contributing to Sustainable Development：The ultra-low loss design makes the 1000 kVA model save about 8,000 kWh of electricity per year under 80% load rate, reducing carbon emissions by about 10 tons per year, contributing to the carbon neutrality goal of industrial enterprises.

Supply Chain Advantages

1.Stable and High-Quality Raw Material Supply System：We have established long-term exclusive strategic cooperation relationships with well-known domestic and foreign raw material suppliers.
2.Strong Customized Production Capacity for 1000 kVA Model：We have a 50+ person professional R&D team including 10 senior engineers and 20 electrical design experts, who can provide personalized customized design for the 1000 kVA model according to the customer's specific application scenarios (such as special environment, special installation space), power grid conditions and special requirements.
3.Rapid Market Response and On-Time Delivery Capability：The production cycle of the standard S13/22-M 1000 kVA model is only 30-45 days, which is 15-20 days shorter than the industry average of 50-60 days, ensuring the rapid delivery of customer orders.

3.Comprehensive After-Sales Maintenance and Fault Handling：We have a 24-hour uninterrupted technical service hotline and online customer service (WeChat, WhatsApp, Email), with a professional technical service team on duty 24 hours a day, providing real-time solutions to the customer's equipment operation, maintenance and fault problems, with a response time of less than 1 hour.

FAQ

Q1: Does the fully sealed transformer require regular oil changes?
A: No, under normal operating conditions, oil changes are not required. The fully sealed design effectively prevents oil oxidation and moisture ingress. However, we recommend oil sample testing every 5–8 years to monitor insulation condition.
Q2: Can the transformer be installed outdoors?
A: Yes, it is suitable for outdoor installation with an IP54 protection rating. To further extend service life, we recommend adding a sun and rain shield, especially in extreme weather conditions.
Q3: Is parallel operation supported?
A: Yes, parallel operation is possible provided that all units have matching rated parameters, including voltage ratio, short-circuit impedance, and connection group, and that proper phase sequence is ensured.
Q4: What is the typical delivery time?
A: For standard models, delivery takes approximately 30–45 days. For units with large capacity or special customization requirements, lead time will vary based on the specific configuration. Please contact our sales team for a detailed schedule.
