1. Scope of application: It is mainly suitable for the connection of medium and light mobile appliances (household appliances, power tools, etc.), instrumentation, and power lighting; the working voltage is AC 750V and below, and most of them are AC 300C.
2. Because the product needs to be moved, bent, twisted frequently, etc., the power cord is required to be soft, stable in structure, not easy to kink, and has certain wear resistance; the plastic sheathed rubber power cord can be laid directly in the soil.
3. The grounding wire adopts yellow-green two-color wire, and other wire cores in the rubber power cord are not allowed to use yellow-green wire cores.
4. When used for the power connection line of electric heating appliances, braided rubber insulated cords or rubber insulated cords should be used as appropriate.
5. The structure is required to be simple and light.
6. Structure
1) Conductive power core: It adopts copper core, the structure is flexible, and it is twisted by multiple single wire bundles; the flexible wire conductor generally adopts the 5th or 6th type conductor structure.
2) Insulation: The insulating material is generally made of natural styrene-butadiene rubber, polyvinyl chloride or soft polyethylene plastic.
3) The cable pitch multiple is small.
4) The outer protective layer is woven with cotton yarn to avoid overheating and scalding the insulating layer.
5) In order to facilitate use and simplify the production process, the three-core balance structure is adopted, which can save production time and improve production efficiency.
