Service

As a source factory focusing on the integration of transformer R&D, production and sales, we have always adhered to the principle of "quality as the foundation and service as the soul". Based on years of in-depth experience in the industry, we provide global customers with full-chain, customized and cost-effective transformer solutions. From pre-consultation to post-sales maintenance, we provide full-process support to make every customer worry-free, assured and at ease.

1. Customized R&D Services

Relying on a professional R&D team and our own R&D center, we break the limitations of standardized products, focus on customers' personalized needs, and provide full-process customized R&D support. With a number of utility model and invention patents, equipped with a professional simulation design platform, we can carry out electromagnetic simulation calculation and structural optimization design according to customers' specific working conditions (such as high altitude, low temperature environment, nonlinear load, etc.), and tailor transformer products suitable for different scenarios (new energy photovoltaic/wind power, power plants, large factories and mines, urban power grids, high-rise buildings, etc.). Our products cover all categories such as oil-immersed, dry-type and special transformers, taking into account core needs such as energy saving, low noise and high efficiency, helping customers maximize product value. At the same time, we can provide complete technical proposals and respond quickly and efficiently to engineering changes.

2. Standardized Production Services

As a source factory, we realize full-process independent control from raw material procurement to product delivery, refuse outsourcing links, and strictly control product quality. Equipped with standardized production workshops, automatic production lines and precision testing equipment, core processes (silicon steel sheet cutting, winding, vacuum impregnation, assembly, etc.) are all completed independently. We have established a complete quality control system from Incoming Quality Control (IQC), In-Process Quality Control (IPQC) to Outgoing Quality Control (OQC). Each product undergoes multiple professional tests such as surge test and inter-turn test to ensure that all performance indicators meet national industry standards and customer requirements. At the same time, we have strong delivery capacity, with sufficient raw material inventory on hand, which can efficiently undertake large-volume orders and urgent orders, ensure on-time delivery, and support OEM/ODM services to help partners expand the market.

3. Omnichannel Sales Services

We uphold the sales philosophy of "direct supply from factory to terminal", eliminate intermediate links, and provide customers with cost-effective first-hand sources without intermediate price premiums. Equipped with a professional sales team, we provide one-on-one exclusive docking services, patiently answer all kinds of customer questions about product selection, parameter specifications, price calculation, delivery cycle, etc., and accurately recommend suitable products and solutions according to customers' project needs. Our sales network covers the whole country, and we can provide national logistics and distribution services, track the logistics status throughout the process to ensure that products are delivered to the site safely and on time. At the same time, we support online and offline synchronous docking, making cooperation negotiation and order follow-up convenient and efficient, and can cooperate with customers to complete inspection and handover to protect customers' rights and interests.

4. Comprehensive After-Sales Guarantee Services

We adhere to the commitment of "no dead ends in after-sales service and endless service", and build a full-cycle after-sales guarantee system to make customers worry-free in use. If there is a quality problem of the product itself within the warranty period, we will provide free repair and replacement services; after the warranty period, we will provide spare parts and maintenance services at the most preferential price. We have opened a 24-hour service hotline. After receiving the customer's fault notification, we will respond within 2 hours and arrange professional after-sales technical personnel within 12 hours domestically and 24 hours overseas to assist in handling installation, debugging, fault repair, and daily maintenance related matters. At the same time, we provide free technical training, regular inspection and quality tracking services, establish a complete user and product file, continuously track the operation status of products, and timely solve various problems encountered by customers in the use process, helping customers' equipment operate stably.

5. Value-Added Supporting Services

To further improve customer experience, we additionally provide diversified value-added services: free technical consultation, product selection guidance and on-site survey services; we can send professional and technical personnel to fully assist customers in product installation and commissioning until the equipment operates normally; according to customer needs, we provide relevant technical training on product use and daily maintenance to improve the operation ability of customers' staff; for key projects, we arrange special personnel to follow up the whole process, providing one-stop exclusive services from R&D, production to delivery and maintenance. At the same time, we can cooperate with customers to optimize cost schemes to achieve mutual benefit and win-win results.

We have always been customer-oriented, deeply rooted in the transformer field, and with professional technology, strict quality and considerate service, we have become a trusted transformer source factory partner for customers, empowering the high-quality development of all walks of life with reliable power solutions.
