Because the wire and cable need to be used in different occasions, will come into contact with air, water, acid and alkali substances, and sometimes even to deal with a variety of harsh environments, so it is necessary to provide different performance according to the use of the environment, such as high temperature resistance, flame retardant, anti-aging, corrosion resistance, etc., the following will introduce the basic performance of several wire and cable in detail, let's take a look.

01 High temperature resistance

High temperature resistance, as the name suggests, means that wire and cable can work in a high temperature environment, delaying the speed of deformation and aging. The rated working temperature of the wire and cable we usually use is generally 70~90 ° C, if it is an ordinary use environment, it is fully competent. However, if you also want to have a higher temperature resistance level, you need to use high-temperature materials to produce wire and cable, such as the newly promoted 105 ° C, 125 ° C new material wire on the market, such as this product to cope with high household electricity load or temporary short circuit more easily.

02 Anti-aging performance

Anti-aging of wire and cable refers to the ability of wire and cable to maintain its original performance under the action of mechanical stress, electrical stress, thermal stress and other various external factors, which can greatly delay aging and extend service life. Although the wire and cable have anti-aging performance, but their aging is inevitable, the difference is that the speed of aging is different, the better the quality of the wire and cable, the slower the aging speed, the longer the service life, which is why we must use big brands, regular manufacturers of products.

03 Corrosion resistance

Corrosion resistance of wire and cable refers to electrochemical corrosion resistance, biological corrosion resistance, chemical (oil, acid, alkali, chemical solvent, etc.) corrosion resistance, salt spray resistance, sunlight resistance, cold resistance, anti-gas and moisture-proof performance. Wire and cable in the process of use can not avoid contact with air, water, acid and other substances, and corrosion resistance can prevent the corrosion of wire and cable in contact with these substances to a certain extent, the speed and degree of weathering, while slowing down the aging rate, extend the service life.

04 Flame retardant performance

Flame retardant is the performance of preventing the spread of flame, which can make the wire and cable not easy to burn in the event of an electrical fire, and to a large extent reduce the flame spread after the wire and cable combustion in the case of continuous combustion, and naturally extinguish after leaving the fire source. Some electrical fires are caused by a short circuit burning somewhere in the wire and cable, which continues to burn along the line, and then cause a fire, flame retardant wire and cable can reduce this risk as much as possible, and a small range of burning will slowly extinguish after leaving the fire source, preventing the spread of flame.

05 Fire resistance

Some people who do not understand the wire and cable industry are easy to confuse the two concepts of fire resistance and flame retardant, and even some bad enterprises false publicity, fuzzy the concept of fire resistance and flame retardant. In fact, fire-resistant wire and cable and flame retardant wire and cable are essentially different, fire-resistant wire and cable more emphasis on the flame burning situation can maintain a certain time of safe operation, to maintain the integrity of the line, more used in high-rise buildings, underground railways, underground streets, large power stations and important industrial and mining enterprises and other places related to fire safety and fire rescue.

Of course, in addition to the above mentioned performance, wire and cable also has tensile and compressive resistance, vibration resistance, wear resistance, impact resistance and other properties, so we usually use the household wire, we must choose wire and cable according to their actual needs. Don't buy some substandard wires for convenience and cause a fire.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
