Lift Rod external line high lifting spiral cable

Time:2021-08-03 View:

High lifting spiral cable belongs to the technical field of power cable.

 

Product Introduction
The high-level lifting spiral cable consists of insulated wire core and sheath. The inner core of the insulated wire core is conductor, the outer layer is insulating layer, and the outer part of the insulated wire core has a sheath layer, its characteristic is that the conductor of the insulated wire core is several wires, the ratio of the stranded section of the wire is less than 12, the ratio of the stranded section of the insulated wire core is less than 12, and the outer part is the extruded thermoplastic elastomer sheath layer.
 
Advantages
Advantages of high lifting spiral cable:
(1) continuous reciprocating motion.
(2) restore the original shape when the external force is revoked to ensure the follow-up.
(3) long life cycle, can complete 3 million cycles.
(4) when the spiral cable is stretched or contracted at the same time, has relative friction with the cable bearing rod, and bears rapid bending, elongation, winding and other movements, the core wire will not crack, classification of external protection spiral cables
Classification
The classification of high lifting spiral cable can be classified by sheath material, which can be divided into four types: PVC spiral cable, PUR spiral cable, PA spiral cable and rubber spiral cable.
PVC spiral cable has the lowest price but the worst performance and is not easy to rebound. It is not as good as other cables in terms of electrical and physical properties. It is mainly used in low-end equipment, such as telephone lines.
The price of rubber spiral cable is higher than that of PVC spiral cable, but it is not widely used in China because of its poor elasticity and easy sticking.
PA spiral cable has the highest price and superior performance in all aspects. However, because its hardness is too high and its resilience is too strong, it is not easy to control during use, so its application scope is not wide.
PUR spiral cable, a new type of spiral cable made of cable material, has a wide range of application and the best performance. PUR spiral cable has many excellent chemical properties, such as oil resistance, hydrolysis resistance, weak acid resistance, weak alkali resistance, aging resistance, ultraviolet resistance, microbial corrosion resistance, and wear resistance, tear resistance, and good elasticity and other excellent physical properties. Gradually becoming the leading spiral cable replaces other types of spiral cable on the market.
Superiority
The structural characteristics of spiral cable make the use of movable equipment more convenient, the retraction and release are no longer messy, and the overall equipment is more beautiful, which is the preferred accessory for movable equipment to improve brand value.
High lifting spiral cable can also be called Spring cable, slingshot cable, spring wire, coil or telescopic wire, etc.
High lifting spiral cable refers to materials used for power, communication and related transmission purposes.
Lifting spiral cable mainly includes: mechanical equipment spiral cable, power spiral cable, communication equipment spiral cable and spiral optical cable.
 
Cable naming
The complete naming of spiral cables is usually complicated, so people sometimes use a simple name (usually a category name) combined with model specifications to replace the complete name, for example, "RVUT3 * 0.5" represents PVC insulated PUR sheathed 3-core 0.5 square spiral cable.
R: represents flexible conductor structure. Spiral cables generally adopt flexible conductor structure with good scalability.
V: The material representing the insulation layer, PVC insulation material.
U: The material representing the sheath layer, PUR sheath material.
T: indicates a spring, that is, a spiral.
Number "3": indicates that the number of insulated wire roots is 3
The number "0.5": indicates a copper conductor with a cross section of insulated wire square meters and a square number of 0.5 square meters.
