High-quality products tailored for wholesalers and distributors worldwide.
Welcome to China Loong Transformer Co., Ltd. We work with global B2B buyers on the supply of electrical power equipment and transformer-related products, including dry type transformers, oil immersed transformers, three phase and single phase power transformers, compact substations, switchgear, distribution boxes, and other custom electrical solutions. Our ordering process is designed to make inquiry, customization, confirmation, and delivery clear and efficient for international projects.
Please begin by sending us your product requirements, application details, and target market standards. To help us recommend the right solution, we encourage you to share specifications such as rated capacity, voltage level, frequency, insulation class, installation environment, cooling method, enclosure type, and any special performance requirements.
If you are sourcing a standard product, you may simply tell us the model, technical data, quantity, and destination. If your project requires a custom design, please include drawings, photos, dimensions, material preferences, color requirements, terminal arrangement, accessories, and packaging expectations. The more detail you provide, the more accurately we can evaluate your request.
After reviewing your inquiry, our team will assess the product structure, materials, configuration, and production requirements before providing a quotation. For custom transformers, switchgear assemblies, compact substations, or distribution solutions, pricing will be based on the technical specifications, order quantity, packaging needs, testing requirements, and delivery terms.
China Loong Transformer Co., Ltd. will communicate any key options that may affect the final offer, such as special enclosures, losses, insulation performance, tap changer configuration, accessories, labeling, or export packing. If your project requires multiple items or a mixed order, we can prepare a quotation according to the different product requirements and quantities.
Once the quotation is accepted, we will confirm the final product details with you before production begins. This may include technical specifications, drawings, dimensions, approval samples, packaging method, order quantity, delivery address, and any other special instructions.
For customized orders, we may request your written confirmation of the approved design, nameplate details, or other order documents before proceeding. If an invoice, proforma invoice, or purchase order is required for your internal process, we can support the necessary documentation according to the agreed transaction terms.
Payment terms are arranged according to the order details, product type, and commercial agreement. We will confirm the acceptable payment method, schedule, and related documents during the quotation and order confirmation stage.
For international B2B orders, the payment arrangement may vary depending on the project scope, customization level, and shipping requirements. Please contact us to discuss the most suitable arrangement for your order, and we will coordinate the terms based on mutual confirmation.
After payment and technical confirmation are completed, production will be arranged according to the approved specifications. Throughout the manufacturing process, we may provide progress updates, technical clarification, or photos when needed to keep the project aligned with your requirements.
Quality control is carried out during production and before shipment to ensure the product matches the confirmed order details. For transformer and electrical equipment orders, checks may involve appearance, dimensions, wiring, assembly, labeling, and other relevant test items depending on the product structure and project requirements. If your order requires additional inspection or third-party coordination, this can be discussed in advance.
Packing will be arranged according to the product type, transportation method, and destination country. We aim to provide protective packaging suitable for export handling, long-distance shipment, and on-site unloading. For larger products such as power transformers, compact substations, or switchgear assemblies, packing and loading methods will be coordinated based on the order size and logistics plan.
Shipping terms, transport mode, and delivery schedule will be confirmed according to the final order requirements. Depending on the destination and project needs, delivery may be arranged by sea, land, or other suitable logistics methods. We will communicate the shipment details clearly before dispatch so that your team can prepare for receipt and installation.
After shipment, China Loong Transformer Co., Ltd. remains available for order follow-up, installation communication, and technical support related to the supplied products. If you have any questions about packing, documentation, product use, or installation coordination, please contact us promptly.
In the event of any issue related to the received goods, please share the order information, photos, and a clear description of the concern so we can review the case efficiently and respond according to the confirmed order terms. We value long-term cooperation and aim to support repeat orders, future project inquiries, and ongoing technical communication with our international partners.
