Home improvement is inseparable from wires, especially old houses. Although the wires are small, the "responsibility" is heavy. Therefore, all owners and friends must keep their eyes open when checking and accepting electric wires, and all take safety as the ultimate goal. If inferior quality wires are used in the home, many problems will occur, and even fires may be caused. Therefore, the inspection and acceptance of the wires is very important. First, the brand of the wire. Specifications, models, etc. must be unified with those stipulated in the contract. We should also pay attention to the anti-counterfeiting marks on the packaging during acceptance. If necessary, you can call the special service number of the wire manufacturer to identify the authenticity of the wire. The counterfeit wire has a relatively thin copper core and poor toughness. The supervisor will use a caliper to measure the diameter of the wire during acceptance and calculate whether it meets the standard. In general, pay attention to the following four items:
1. Inspect the certificate according to the batch, and the certificate should have the production license number.
2. Appearance inspection: the packaging is intact; the wire insulation layer of the random inspection is intact and uniform in thickness; the heat-resistant and flame-retardant outer sheath of the wire has an obvious mark and manufacturer's mark.
3. According to the manufacturing standards, on-site sampling inspection of the thickness of the insulation layer and the diameter of the round core. The core diameter error should not be greater than 1% of the nominal diameter; the thickness of the insulation layer of the commonly used BV insulated wire should not be less than the value specified in Table 3.7.
4. If there is any objection to the insulation performance, electrical conductivity and flame retardancy of the wire, samples shall be sent to a qualified laboratory for testing in batches.
