Cable reels are often used in our production and life, and the safety of cable reels has become an important link related to the safety of the entire production. So you know what kind of cable reel is safe, and how can you choose a safe cable reel? First, the cable reel option has leakage protection. During the use of the cable reel, there will be different degrees of leakage due to moisture, damage, aging of wires or products, and harsh use environments. When the leakage current reaches 30 mA, the human body becomes numb or convulsed, causing damage to the brain, heart and nerves, and the child is at risk of fainting. Choose a cable reel product with a high-sensitivity residual current protector. Products with this function are sensitive to circuit drain electrodes. When the leakage current is greater than 10 mA, the power supply will be cut off, and the protector will automatically trip and cut off the power supply for protection. The response time is less than 0.1 seconds, and the protection function of the product will still work when the ground wire fails. Second, the cable reel must have overload protection. Cable reel is a kind of electrical equipment with relatively large load and power. In industrial production, it is impossible to equip an electrical appliance with a cable reel. A product is often connected to a variety of electrical appliances, and electrical overload often occurs. The overload protector used in the superior cable reel has high sensitivity. When the current load does not exceed the rated load of the cable reel, the overload protector will not activate. When the current load exceeds the rated load of the cable reel, the overload protector will issue a warning and cut off the power within a certain period of time. The higher the load, the faster the power will be cut off. At the same time, its overload protection function can be restored, and it can be restored to normal by pressing the overload protection switch, and it can be reused without replacing the fuse or fuse tube. It is easy to use and can effectively protect electrical equipment and household electricity safety. three. Protection against external security threats: Swivel cover and waterproof cover. In the safety of electricity use, a very important danger is “electric shock”, and the socket at home is a great source of danger for children. To this end, many sockets are equipped with safety gates. In industrial production, this protection is also necessary. On the one hand, it can prevent children from accidentally touching it, and on the other hand, it can also prevent dust and debris from falling outside. Another important safety measure is the waterproof and rainproof function. The industry is often carried out outdoors, and the rain and snow are unpredictable, so the cable tray is required to be waterproof and rainproof.
