Some knowledge points of wire and cable, wire and cable professional manufacturers tell you

Professional manufacturers of wire and cable think that when detecting the DC resistance of wire and cable, the actual conductivity of wire and cable should be detected first. Therefore, DC resistance data can directly reflect the quality of data in wire and cable and the primary conductivity of wire and cable. In the actual test, when the actual section width of the wire and cable is larger than normal, the greater the current through the wire and cable, the greater the resistance, and vice versa.

Some knowledge points of wire and cable, wire and cable companies tell you

Wire and cable companies believe that wire and cable need to be used in different situations, will come into contact with air, water, acid and alkali substances, etc. Sometimes even have to deal with a variety of harsh environment, so need to have different performance according to different requirements. The rated operating temperature of common wires and cables is generally 70 to 90. If it's a normal environment, you can do it. If you want to have higher temperature resistance rating, you need to use high temperature resistant materials to produce wire and cable, such as 105 and 125 new materials on the market.

The characteristics of wire and cable, wire and cable company for you to explain

Wire and cable companies believe that in the structural design, production and selection of wires and cables, electrical properties (including conductivity, insulation and transmission characteristics), mechanical and physical properties, aging properties, compatibility between materials and other properties (such as metal hardness, creep, non-flame retardant, radiation resistance of polymer materials, etc.). Materials must be considered according to the use of the product, application requirements and laying environment. This requires a thorough understanding of metallurgy, metal working, electroplating, polymer materials, dielectric chemistry, electrical insulation, polymer rheology and heat transfer.

What are the structures of wire and cable? Wire and cable company to introduce you

Wire and cable companies are reminded that the vast majority of wire and cable products are products with the same section (cross section) shape (ignoring manufacturing errors), the strip shape, which is determined by the characteristics of the system or equipment used as a wire or coil. Therefore, wire and cable companies study and analyze the structural composition of cable products, just observe and analyze its cross section. Generally speaking, the structural elements of wire and cable products can be divided into conductor, insulating layer, shielding and protective layer as well as filling elements and tensile elements of four main structural components, according to the requirements of the use of products and application occasions, the structure of some products is very simple.

Some common sense of wire and cable, wire and cable company for you

Wire and cable companies consider eco-friendly cables to be free of heavy metals such as lead, cadmium and mercury. Free of brominated flame retardants. Environmental performance test approved by SGS, in line with EU Environmental Protection Directive (RoSH), higher than its index requirements. No harmful halogen gas, no corrosive gas, small calorific value during combustion, no soil pollution wire and cable. There is no hard and fast line between "wire" and "cable." Usually the products with less core, small diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables.

Wire and cable company describes the problems that need to be paid attention to when using cables

Wire and cable company describes the problems that need to be paid attention to when using cables Wire and cable as the key components of the power engineering system, in use must be regularly maintained and maintained, which can ensure our own daily safety of electricity, at the same time can extend the use of wire and cable, cable in daily use need to pay attention to the problems:

What is the cable safety storage method introduced by wire and cable company?

Wire and cable company: wire and cable as a hazard to personal safety, capital safety commodities, has been included in the department supervision and management to a point, professional manufacturers according to the cycle time to accept the inspection of the watchdog. Therefore, the supplier should be able to give the inspection report of the quality control department, otherwise, the quality of wire and cable products is lack of basis.

Wire and cable company introduces how to distinguish the continuous high temperature wire and cable true or false

Wire and cable company: high temperature cable as their name has the same heat resistance, the characteristics are usually formed by the production and processing of special raw materials, but also made high temperature cable is more expensive than other cable, although more expensive, but the role can not be measured with money. Continuous high temperature wire and cable are ubiquitous in our daily life and widely used. It also brings great convenience to our daily life. Moreover, continuous high temperature wire and cable have many advantages compared with general cables.

Guangdong cable manufacturer: Talk about the matters to pay attention to when choosing cables

Guangdong cable manufacturer: Cable model specifications generally refer to copper cable VV, YJV and other specifications. The corresponding size of cable model specifications, such as cable carrying capacity, is a very important reference basis for the selection of cable model.
