How to solve the problem of overheating of wires
Overheated wires are a common safety hazard in homes and industrial electricity and can lead to fires or equipment damage. Recently, the issue of wire overheating that has been hotly discussed throughout the Internet mainly focuses on cause analysis, solutions and preventive measures. This article will combine the hot content of the past 10 days to provide you with detailed solutions.
1. Main causes of wire overheating
| Reason type | Specific performance | Proportion (whole network data) |
|---|---|---|
| overload | The current exceeds the carrying capacity of the wire | 42% |
| Poor contact | Connectors are loose or oxidized | 28% |
| Aging of wires | The insulation layer is damaged or the material is deteriorated | 18% |
| environmental factors | High temperature confined space or direct sunlight | 12% |
2. Solution to wire overheating
Based on recent popular discussions on professional electrician forums, we have compiled the following solutions:
| Problem level | solution | Operation difficulty |
|---|---|---|
| slight fever | 1. Reduce the number of electrical appliances used at the same time 2. Check and tighten all joints | ★☆☆☆☆ |
| Obvious fever | 1. Replace wires with larger cross-sectional area 2. Install temperature monitoring device | ★★★☆☆ |
| severe fever | 1. Cut off the power immediately 2. Ask a professional electrician to perform a complete overhaul | ★★★★★ |
3. Effective measures to prevent wire overheating
According to safety tips issued by the fire department in the past 10 days, preventive measures include:
1.Regular inspection: It is recommended to check the home circuit every six months, focusing on old lines and joints.
2.Reasonable wiring: Avoid entanglement or pressure on wires and maintain a well-ventilated wiring environment.
3.Choose quality materials: Use national standard wires, copper core wires are better than aluminum core wires, and the cross-sectional area must meet the load requirements.
| Electrical power | Recommended minimum wire diameter | Safe carrying capacity |
|---|---|---|
| ≤1000W | 1.0mm² | 10A |
| 1000-2000W | 1.5mm² | 15A |
| 2000-3500W | 2.5mm² | 20A |
4. Recent relevant hot events
1. A fire broke out in a community due to overheating of an electric vehicle charging cable, injuring three people (July 15).
2. The State Administration for Market Regulation released the results of spot inspections on the quality of wire and cable products, showing that the unqualified rate reached 12.5% (July 18).
3. A well-known home appliance brand recalled some products due to the risk of overheating in the power cord (July 20).
5. Expert advice
Electric power expert Professor Li emphasized in a recent interview: "Overheating of wires is a gradual process and is often ignored in the early stages. It is recommended that households be equipped with infrared thermometers and regularly detect the temperature of wire joints. If it exceeds 65°C, it should be repaired immediately."
Safe use of electricity is no small matter. Timely detection and solution of wire overheating problems can effectively prevent electrical fire accidents. In case of complicated situations, be sure to contact a professional electrician to deal with it, and do not take risks on your own.
