Factory direct sales - solid capacitor - patch aluminum electrolysis, to ensure that the factory first-class goods!

1. In order to ensure the safety of the power consumption of the factory, the mobile power equipment such as the floor fan and the hand drill must be installed with the leakage protection switch. The leakage protection switch should be checked frequently. Try to jump no less than once a month. If there is a malfunction, replace it immediately. After the fuse is blown or the leakage protection switch is tripped, the cause must be ascertained, and the fault can be restored before the power transmission can be resumed.

2. Never replace the fuse with copper wire, aluminum wire or iron wire. Replace the air switch immediately after it is damaged. The size of the fuse and air switch must match the power capacity. Otherwise, it may cause electric shock or electrical fire.

3. The metal casing of the electrical equipment must be reliably connected with the protection wire. The single-phase power should be connected by the three-core cable, and the three-phase power should be connected by the four-core cable. Protection is securely connected to the protective neutral or grounding device of the low voltage grid outdoors. The protective neutral must be grounded repeatedly.

4. The mouth or damage of the cable or wire should be wrapped with electrical tape. It should not be replaced by medical tape, and it should not be wrapped with nylon paper. Do not use wires directly into the socket to use electricity.

5. When the appliance is found to emit smoke, emit a burnt smell or catch fire, the power should be cut off immediately. Do not use water or foam fire extinguisher to extinguish the fire.

6. Do not touch the lamp head, switch, plug and socket and electrical appliances with wet hands. If the switch, socket or electrical appliance is damaged or the casing is damaged, it should be repaired or replaced in time. It can not be used without repair.

7. The wires in the factory building cannot be connected indiscriminately. It is forbidden to use multiple ports and old wires to prevent electric shock. For the installation of electrical equipment, you must pass the qualified electrician and strictly implement the relevant device regulations. If you let something that you don't know how to do it, or if you don't follow the relevant device rules to throw the wires, you will have many unsafe factors.

8. Electric furnaces such as electric furnaces and electric soldering irons should not be placed directly on the wooden board or close to flammable materials. If the electric heating equipment without automatic control is used, the power supply should be turned off to avoid fire.

9. Mobile electric appliances in the factory, such as floor-mounted fans, hand-held grinders, hand drills and other power tools must be installed with the leakage protection switch to implement single-machine protection.

10. If someone is found to have an electric shock, do not use any hand to pull the electric shock. Open the power switch as soon as possible or use a dry wooden stick or bamboo pole to pick up the wire and immediately use the correct artificial respiration method for on-site rescue.

11. The installation and maintenance of electrical equipment shall be the responsibility of the licensed electrician.

12. The theft of power facilities jeopardizes public safety, destroys industrial and agricultural production, and disrupts people's lives and electricity. Everyone reports them.
