Overview

MHYSV signal cable-5x2x0.5 in stock $r $n, because the insulation material is required to have excellent electrical insulation properties, the purity and impurity content of the material must be extremely low; Often unable to balance its ability to protect the outside world, various protective layer structures must be used to withstand or resist various mechanical forces from the outside world (i.e. installation, usage, and in use), withstand atmospheric environments, resist chemicals or oils, prevent biological damage, and reduce the harm of fires.

MHYSV signal cable-5x2x0.5 in stock

Wire and cable are used to transmit electrical (magnetic) energy, information, and implementationelectromagnetic energyConverted wire products. Broadly speaking, wires and cables are also referred to as cables. Narrowly defined, cables refer to insulated cables, which can be defined as a collection of the following components:; One or more insulatorscore, as well as their respective potentialcoatingThe total protective layer and outer protective layer, as well as additional uninsulated conductors, can also be added to the cable.

The main features of this type of product are: pure conductor metal, no insulation andSheath layer, such asaluminum conductor steel reinforced (ACSR)、Copper aluminum busbar、Electric locomotive lineWait; The main processing technology is pressure processing, such as meltingrolling、Drawing and drawing、strand/Tight compression twistingWait; The product is mainly used in suburban areas, rural areas, user main lines, switchgear, etc.

In a sense, the wire and cable manufacturing industry is an industry of material precision machining and assembly. Firstly, the amount of materials used is enormous, with material costs in cable products accounting for 80-90% of the total manufacturing cost; Secondly, there are many types and varieties of materials used, with specific performance requirements. For example, copper is used as a conductor, and the purity of copper is required to be above 99.95%. Some products require the use of oxygen free high-purity copper; The selection of materials will have a decisive impact on the manufacturing process, product performance, and service life.

At the same time, the benefits of wire and cable manufacturing enterprises are closely related to whether they can scientifically save materials in material selection, processing, and production management.

Therefore, when designing wire and cable products, it is necessary to choose materials simultaneously. Generally, several materials are selected and determined through process and performance screening tests.

The materials used in cable products can be divided into conductive materials according to their usage location and functioninsulating materialFilling materials, shielding materials, protective layer materials, etc. But some of these materials are common to several structural components. Especially thermoplastic materials such as polyvinyl chloride, polyethylene, etc. can be used on insulation or sheath by changing some of the formula components.

The materials used in the manufacturing of cable products involve a wide range of categories, with a particularly large variety of specifications (grades).

3. Name and materials of product structure

(1) Wire: The most basic component of a product for transmitting current or electromagnetic wave information.

Main materials: Wire is the abbreviation for conductive core, made of non-ferrous metals with excellent conductivity such as copper, aluminum, copper-clad steel, copper-clad aluminum, etcoptical fiberAs a wire.

There are bare copper wires and tin plated wires; Single branch line, stranded wire; Twisted tin plated wire.

(2) Insulation layer: It is a component that wraps around the periphery of a wire to provide electrical insulation. It can ensure that the transmitted current, electromagnetic waves, or light waves only travel along the wire and do not flow outside, and that the potential on the conductor (i.e., the potential difference formed by surrounding objects, i.e., voltage) can be isolated. This ensures both the normal transmission function of the wire and the safety of external objects and people. Wires and insulation layers are two basic components that must be present in cable products (excluding bare wires).

Main materials: PVC, PE, XLPE, polypropylene PP, fluoroplastic F, rubber, paper, mica tape

(3) Filling structure: Many wire and cable products are multi-core. After these insulated cores or wires are paired into cables (or grouped multiple times into cables), one reason is that the shape is not round, and the other is that there is a large gap between the insulated cores. Therefore, filling structure must be added during cable formation. The filling structure is designed to make the outer diameter of the cable relatively round to facilitate tape wrapping and sheath extrusion.

The main feature of this type of product is that it is extruded (wound) outside the conductorPackage insulation layer, such asOverhead insulated cable, orSeveral cores twisted together(Corresponding to the phase lines, neutral lines, and ground lines of the power system), such as overhead insulated cables with two or more cores, or additional protective sheaths, such as plastic/Rubber sheathed wire and cableThe main process technologies include drawing, twisting, insulation extrusion (wrapping), cabling, armor and protective layer extrusion, etc. The different process combinations of various products have certain differences.
