Do you know what materials are available for Cable Protector covers
The Cable Protector sleeve is the outermost layer of the cable, as the most important barrier to protect the internal structure of the cable, and protects the cable from mechanical damage during and after installation.Cable Protector sleeves are not intended to replace the reinforced armor inside the cable, but they can provide a fairly high level but limited means of protection. In addition, the cable jacket also provides protection from moisture, chemicals, ultraviolet rays and ozone. So, what are the materials for the Cable Protector sleeve?
1.Cable Protector cover material: PVC
The cable material is made of polyvinyl chloride as the basic resin, adding stabilizers, plasticizers, and additives such as calcium carbonate and other inorganic fillers, additives and lubricants, and then mixed, kneaded and extruded particles.
Polyvinyl chloride can be formulated to be used in various environments and applications. It has low cost, good flexibility, quite strong, and has fire/oil proof materials.
However, this material contains substances harmful to the environment and the human body, and there are many problems when applied to special environments. With the enhancement of people's awareness of environmental protection and the improvement of material performance requirements, higher requirements are put forward for PVC materials.
2.Cable Protector cover material: PE
Due to its excellent electrical insulation properties and good processing properties, polyethylene is widely used as a coating material for wires and cables, and is mainly used in the insulation and sheath layers of wires and cables.
Excellent electrical performance and extremely high insulation resistance. Polyethylene can be hard and very hard, but low-density PE (LDPE) is more flexible and has excellent moisture resistance. Properly formulated PE has excellent weather resistance.
The linear molecular structure of polyethylene makes it very easy to deform at high temperatures. Therefore, in the application of PE in the wire and cable industry, the polyethylene is often cross-linked to make the polyethylene into a network structure, which makes it strong at high temperatures. Resistance to deformation.
Cross-linked polyethylene (XLPE) and polyvinyl chloride (PVC) are both used as insulation materials for wires and cables, but XLPE wires and cables are more environmentally friendly than PVC wires and cables, and at the same time they have better performance.
3.Cable Protector cover material: PUR
PUR cable is one of the cables. The material of PUR cable has the advantages of oil and wear resistance, while PVC is made of ordinary materials. In the cable industry in the past few years, the position of polyurethane has become increasingly important. At a certain temperature, the mechanical properties of this material are similar to those of rubber. The combination of thermoplasticity and elasticity results in TPE thermoplastic elastomer.
It is widely used in industrial machinery and equipment, transmission and transmission control systems, various industrial sensors, testing instruments, electronic appliances, household appliances, electromechanical, kitchen and other equipment, and used for power supply and signal connection in occasions such as harsh environment and oil-proof.
4.Cable Protector cover material: TPE/TPR
Thermoplastic elastomers have excellent low-temperature properties without the capital required for thermosetting materials. It has good chemical and oil resistance, and is very flexible. Good abrasion resistance and surface texture, but not as durable as PUR.
5.Cable Protector cover material: TPU
Polyurethane cable refers to a cable that uses polyurethane material as insulation or sheath. Its super abrasion resistance refers to the super abrasion resistance of the cable Protector sheath and insulation layer. The polyurethane material used in cables is generally called TPU, which is thermoplastic polyurethane elastomer rubber. Mainly divided into polyester type and polyether type, hardness range (60HA-85HD), wear resistance, oil resistance, transparency, good elasticity, TPU not only has excellent high wear resistance, high tension, high tensile strength, toughness and It is resistant to aging and is a mature environmentally friendly material.
The application fields of polyurethane sheathed cables include marine application cables, industrial robots and manipulator cables, port machinery and gantry crane cables, and mining engineering machinery cables.
6.Cable Protector cover material: Thermoplastic CPE
Chlorinated polyethylene (CPE) is usually used in very harsh environments. It has the characteristics of light weight, very hard, low friction coefficient, good oil resistance, good water resistance, excellent chemical resistance and UV resistance, and low cost.
7.Cable Protector cover material: ceramic silicon rubber
Ceramic silicon rubber has excellent fire-retardant, flame-retardant, low-smoke, non-toxic and other characteristics. The extrusion molding process is simple. The residue after combustion is a hard ceramic shell. The hard shell does not melt and does not melt in a fire environment. Dripping can pass GB/T19216.21-2003 at 950℃-1000℃ temperature, 90min fire, 15min cooling line integrity test, suitable for any place where fire prevention is required, and smooth power transmission under fire conditions Played a strong protective role.
Ceramic silicon rubber products have no special requirements for equipment and simple processing technology. Traditional silicon rubber processing equipment can be used to achieve production. Compared with the current production technology of fire-resistant wires and cables, it has higher production efficiency and can reduce production energy consumption and cost.
The above is the whole content of the materials of the cable Protector sleeve.In fact, there are many types of cable Protector sleeves. When choosing the raw material of theCable Protector sleeve, the compatibility of the connector and the adaptability to the environment should be considered.
Steel Solid Rigid Centralizer is generally used in regular holes without neck shrinkage or large belly section. When the well diameter reaches a certain level, no amount of rigid centralizers can make the casing reach the desired medium.
