First, the cause of the quality of the cable itself
1. The quality of the cable itself is too bad, and the manufacturing process of the intermediate terminal of the link terminal is not good, or the crimping is not tight, the connection is not good, the connector is oxidized during operation, and the decapping results in explosion and fire.
2. Years of operation lead to insulation aging and short circuit fire.
3. The cable is overloaded for a long period of time. The fuse can't timely remove the short-circuit current caused by the load and cause the insulation to overheat, causing short circuit and fire.
4. Mechanical damage to the cable caused by external forces causes the insulation of the cable to break short-circuit and catch fire.
5. Oil leakage caused by oil spilled cable. When the height difference of oil immersed cable laying is large, cable smashing may occur. The moisture and oil leakage of the cable increase the probability of fire failure.
Second, the causes of fire caused by external factors
1. During the construction process, slag ignition cables are used for electric welding cutting metal.
2. Electrical equipment failure A fire causes the cable to catch fire.
3. Improper fire prevention measures in cable tunnels and impregnation of power cables with water will reduce the insulation resistance of cables and cause fire to the grounding or short circuit of cables.
4. The explosion of the milling system caused the cable to catch fire.
5. Rat damage is also one of the causes of cable fire.
Third, preventive measures
1. To create a good construction environment, to ensure construction quality, to prevent the aging of the wire and cable insulation and damage due to the harsh environment.
2. According to the reasonable selection of cables for the load, the capacity of the cables is left as much as possible.
3. Improve the blocking measures for the middle connector of the cable. Check the cable terminal and the middle connector regularly to ensure that the cable connector does not ignite the adjacent cable if it catches fire.
4. Inspect the circuit regularly to prevent external forces from damaging the damaged cable.
5. Do a good job of preventing accidents and drills, and improve the staff's ability to deal with sudden fire accidents so as to prevent the spread of fire.
5. Strengthen the device of fire extinguishing equipment, install an effective fire alarm to deal with the fire situation in time, so as to minimize the damage.
Here are some key features and benefits of using a PU system for shoe soles:
1. Cushioning: PU provides excellent cushioning and shock absorption properties, making it ideal for footwear that requires high levels of comfort and impact protection.
2. Lightweight: PU is a lightweight material, which helps reduce the overall weight of the shoe, making it more comfortable to wear and reducing fatigue during extended use.
3. Flexibility: PU offers good flexibility, allowing the shoe sole to bend and flex with the natural movement of the foot. This enhances comfort and prevents stiffness or discomfort during walking or running.
4. Durability: PU is highly durable and resistant to wear and tear, making it suitable for long-lasting shoe soles. It can withstand repeated use and exposure to various environmental conditions without losing its structural integrity.
5. Slip resistance: PU can be formulated with specific additives to enhance its slip resistance properties, providing better traction and grip on different surfaces. This is especially important for safety footwear or shoes used in slippery conditions.
6. Design versatility: PU can be molded into various shapes and designs, allowing for greater design flexibility and customization options for shoe soles. This enables manufacturers to create unique and visually appealing footwear.
7. Water resistance: PU can be made water-resistant or waterproof, which helps protect the shoe sole and the foot from moisture, rain, or other wet conditions.
Overall, a PU system for shoe soles offers a combination of comfort, durability, flexibility, and design versatility, making it a popular choice for footwear manufacturers and consumers alike.
Wire and cable are indispensable materials for the construction process. Once the cable catches fire, it will cause serious fires and power cuts. In addition, the cable generates a lot of smoke and toxic gas when it burns, which not only pollutes the environment, but also endangers people's lives. To this end, attention should be paid to the fire protection of power cables. The cause of the fire of wires and cables is the quality of the cable itself and external factors.
