I. Submission of Order Information (Ⅰ) For Design Drawings That Have Passed the Drawing Review Complete information is required to facilitate accurate production: 1. Primary main wiring diagram of the engineering system, which clearly presents the system architecture; 2. Secondary principle wiring diagrams for each high-voltage cabinet scheme to ensure the accuracy of electrical control logic; 3. Cabinet layout plan (if a bus bridge is included, the installation dimensions and arrangement method must be attached); 4. Quantity, specifications and models of switchgear spare parts to facilitate later operation and maintenance; 5. Special operating environment conditions (such as high temperature, high humidity, altitude, corrosion, etc.) to adapt to special scenarios; 6. Requirements for cabinet or panel paint color to unify appearance standards. (Ⅱ) Entrusted Design of Principle Drawings Key information needs to be supplemented to improve the design basis: 1. Power supply reply materials to clarify the power supply scheme; 2. Switchgear model, arrangement method, models and parameters of circuit breakers and other switches to consolidate the equipment foundation; 3. Brand requirements for secondary protection (such as microcomputer integrated protection) to standardize protection configuration; 4. Requirements of the local electric power bureau for special electric energy metering cabinets to meet the grid connection standards; 5. The same requirements as those for "existing drawings" mentioned above regarding spare parts, environmental conditions, paint color, and delivery date. II. Instructions for Ordering Process 1. Consultation and communication: Consult about products, prices, inventory, etc. through email (it@fjxfdq.com), phone [+86+13806977339 (press and hold * on a smartphone to turn it into "+")] or online customer service on the official website. The customer service will respond within 24 hours (relevant materials can be downloaded in "Material Download" under "Contact Us", the same below). 2. Submit order: After confirming the demand, fill in the standard order on the official website (including product information, delivery address, contact person, etc.) and send it to the designated email address. 3. Order confirmation: The order will be reviewed within 1-3 working days upon receipt. The inventory, price and delivery date will be confirmed, and an order confirmation letter will be sent. 4. Payment: Within 5 working days after receiving the confirmation letter, make payment by T/T (Telegraphic Transfer) or L/C (Letter of Credit, the terms of which must be consistent with the order). 5. Arrange delivery: After receiving the full payment, deliver the goods according to the delivery date in the confirmation letter, and simultaneously provide logistics information and customs clearance documents (bill of lading, packing list, etc.). III. After-sales Service and Quality Assurance 1. Products meet quality standards and have undergone strict testing; if quality problems are found within 7 days after receipt, please contact us with evidence, and we will handle them properly (return, replacement / repair). 2.
