Correct use of cloth wires (insulated wires)


With the rapid development of the technology era, home appliances can only penetrate more and more into the lives of residents. Security systems, video surveillance systems, temperature control systems, etc. make everyone's life more and more convenient. As a result, the wires and cables in the house are criss-crossed, densely distributed, the utilization rate and the use market are increasing, increasing the incidence of power failure and leakage, and there is a high probability of electric shock accidents. Therefore, everyone must have a new understanding of the use of wires and cables, improve their own safety awareness, and ensure the safety of life and property.

 With the rapid development of the technology era, home appliances can only penetrate more and more into the lives of residents. Security systems, video surveillance systems, temperature control systems, etc. make everyone's life more and more convenient. As a result, the wires and cables in the house are criss-crossed, densely distributed, the utilization rate and the use market are increasing, increasing the incidence of power failure and leakage, and there is a high probability of electric shock accidents. Therefore, everyone must have a new understanding of the use of wires and cables, improve their own safety awareness, and ensure the safety of life and property.

The difference between single core wire and multi core wire

The so-called electric wire refers to a wire covered with an insulating layer, a general-purpose single-core hard conductor unsheathed wire, suitable for connecting wires of power devices, instrumentation appliances, etc., or installation wires with an AC voltage of 450/750V and below.

Commonly used building wires and cables include sheathed cables for BV fixed layout, sheathed flat cables for BVVB fixed layout, BYJ low-smoke halogen-free wires, BV fixed layout hard wires, BVR fixed layout soft wires, etc.

The single-core wire is relatively hard, and the multi-core wire is relatively soft, and the multi-core wire is used for laying in the corners or special places.

                                             

Causes of wire heating

1. The wire cannot carry the excessive power brought by the electrical appliances used in the circuit,

2.The wire resulting in excessive load current and causing heat.

How to prevent damage to wires

In the process of using cloth wires in daily production and household activities, there will be occasional short circuit, burnout, aging and other bad phenomena. We can learn about some effective means of preventing wire damage in advance, and take emergency measures in advance.

(1) Do not expose the wires to moisture, heat, corrosion or bruises, or pressure injuries. Try to avoid the wires passing through places with high temperature, high humidity, and corrosive steam and gas. The wires need to be prepared in advance when they pass through places that are easily bruised. Safeguard.

(2) The current of the electric wire used should not exceed the safe carrying capacity of the wire.

(3) Regular maintenance and inspection of the lines, timely repairs if defects are found, and timely replacement of obsolete and aging wires to ensure the normal operation of the lines.

Electric shock first aid knowledge

(1) Turn off the power

In the event of an accident, the person with electric shock is close to the power source, and the rescuer should choose a tool with insulation to turn off the switch. If the person with electric shock is too far away from the power source, the rescuer can use insulation such as wooden sticks and rubber to separate the electric shock person from the power source.

(2) Emergency rescue

After the electric shock occurs to the human body, it will soon endanger life and safety. Therefore, after the exit point personnel are disconnected from the power supply, they need to be rescued in time to keep the surrounding air smooth. The electric shock person needs to be transferred to a safe environment for rescue in time to avoid other accidents at the scene safety hazards and ensure the best rescue opportunity.

 

Zhengzhou Jinshui cable produces wires and cables that meet the standards. When using wires and cables, everyone should use them in accordance with their specified voltage and standards to avoid potential safety hazards.
