China Custom Air Conditioning (HVAC) Connection Cable

I. Customization process and core parameters
‌Requirement confirmation‌
‌Application scenario‌: clarify the air conditioning type (home/commercial/new energy vehicle), power requirements (such as 3-horsepower cabinet requires 4 square copper core wire) and special environmental requirements (such as high temperature resistance, vodotěsný)‌14.
‌Functional requirements‌: determine whether integrated signal transmission, anti-interference shielding layer or multi-core configuration (such as five-core cable including power + communication line) is required.

‌Design and material selection‌
‌Wire core material‌: Pure copper core wire (RV type multi-strand soft wire or flat hard sheathed wire) is preferred to ensure conductivity and corrosion resistance‌.
‌Sheath material‌: Select flame-retardant PVC, oil-resistant corrugated pipe or waterproof silicone sheath according to the environment, and outdoor scenes need to enhance anti-aging performance‌.
‌Certification standards‌: Must comply with ISO9001/TS16949 quality system and RoHS/REACH environmental protection standards‌.

‌Sample testing and mass production‌
After the supplier provides the sample, it is necessary to test the insulation (withstand voltage ≥ 1500V), current carrying capacity (such as 4 square wire carrying 25A current) and signal stability‌.
After confirmation, mass production is carried out, and the delivery cycle is usually 7-15 days (depending on the complexity)‌.

2. Supplier selection suggestions
‌Professional manufacturer recommendation‌
‌Huakai Wiring Harness‌: Rich experience in customizing high-voltage wiring harnesses for automotive air conditioners, supports withstand voltage design above 300V, and is suitable for new energy vehicle scenarios‌.
‌Xiaoteng Electronics‌: Provides UL certified wires (such as UL1015/2464) and JST/Molex brand connectors, and supports intelligent temperature control system integration‌.
‌Jiacheng Electric Appliance Factory‌: Good at small batch customization, can process cold-pressed terminals, waterproof plugs and multi-core signal harnesses, and the cost is controllable‌.
‌Huahong Company‌: Complies with EU environmental protection standards, and the dedicated wiring harness for central air conditioners supports multi-protocol communication interfaces‌8.

‌Service Comparison‌
‌Price Range‌: Ordinary on-hook wiring harness (1.5 square) is about 1-5 yuan/m, high-voltage cabinet wiring harness (4 square shielded wire) is about $1.5/M.
‌Value-added Service‌: Some manufacturers provide free drawing design, logistics packaging and after-sales warranty (such as 1-year warranty).

III. Notes
‌Compatibility Verification‌: Customized wiring harnesses must match the air-conditioning controller interface (such as terminal size, plug PIN definition).
‌Installation Specifications‌: Power lines and signal lines must be laid in separate casings, and the refrigerant pipes and cables must be kept at a distance and fixed independently to avoid interference or wear.
‌Risk Avoidance‌: The contract must clearly specify the wire specifications, testing standards and liability for breach of contract to prevent inferior products or delayed delivery.

Through precise demand docking and cooperation with compliant suppliers, air-conditioning connection cable customization can be completed efficiently to ensure system safety and long-term stability.
