螺旋电缆命名

Nomenclature of spiral cable

螺旋电缆的完整命名通常较为复杂，所以人们有时用一个简单的名称(通常是一个类别的名称)结合型号规格来代替完整的名称，如“RVUT3*0.5”代表PVC绝缘PUR护套3芯0.5平方的螺旋电缆。

The complete naming of a spiral cable is usually more complex, so people sometimes use a simple name (usually a category name) to combine the model specifications to replace the complete name, such as "RVUT3*0.5" representing a PVC insulated PUR sheath with a 3 core 0.5 square spiral cable.

R:代表软导体结构，螺旋电缆一般均采用软导体结构，伸缩性好。

R: represents the structure of soft conductors. Helical cables are generally constructed with flexible conductors with good flexibility.

V:代表绝缘层的材料， PVC绝缘料。

V: represents the material of the insulating layer, PVC insulating material.

U:代表护套层的材料，PUR护套料。

U: represents the material of the sheath and the PUR sheath.

T:表示弹簧，也即是螺旋。

T: means a spring, that is, a spiral.

数字“3”：表示绝缘线的根数为3根

Number "3": the number of roots of the insulated line is 3

数字“0.5”：表示绝缘线的导体截面平方数为0.5平方的铜导体。

The number "0.5": the copper conductor representing the square of the conductor section of the insulated conductor is 0.5 square.

螺旋电缆的分类

Classification of spiral cables

螺旋电缆的分类可通过护套材料进行分类，主要可分为：PVC螺旋电缆，PUR螺旋电缆，PA螺旋电缆，和橡胶螺旋电缆四大种。

The classification of the spiral cable can be classified by the sheath material, which can be divided into four main types: PVC spiral cable, PUR spiral cable, PA spiral cable, and rubber spiral cable.

PVC螺旋电缆价位*但性能*差，不易回弹，在电气性能及物理性能方面都不及其他电缆，主要用在低端设备种，如线。

The PVC spiral cable has the lowest price but the worst performance. It is not easy to rebound. It is inferior to other cables in terms of electrical and physical properties. It is mainly used in low end equipment, such as telephone line.

橡胶螺旋电缆，价位高于PVC螺旋电缆，但应为其弹性不佳及容易沾粘在国内并未得到广泛应用。

The rubber spiral cable has a price higher than that of the PVC spiral cable, but it should not be widely used in China because of its poor elasticity and easy sticking.

PA螺旋电缆，价位*，各方面性能优越，但因为其硬度太高，回弹性过强，在使用过程中不易控制，故应用范围并不广泛。

PA spiral cable, the highest price, all aspects of superior performance, but because of its too high hardness, too strong resilience, in the process of use is not easy to control, so the scope of application is not widely.

PUR螺旋电缆，一种新型的电缆材料制成的螺旋电缆，适用范围广泛，性能**。PUR螺旋电缆具有耐油耐水解，耐弱酸弱碱，抗老化，防紫外线，防微生物腐蚀等多种优异的化学性能，及耐磨，抗撕裂，和弹性佳等多种优异的物理性能。逐渐成为主导型螺旋电缆替代着市场上的其他类型螺旋电缆。

PUR spiral cable, a new type of spiral cable made of cable material, has wide application and best performance. PUR spiral cable has many excellent chemical properties, such as oil resistance, resistance to hydrolysis, weak acid and weak alkali, anti aging, anti ultraviolet, anti microbial corrosion, and many excellent physical properties, such as wear resistance, tearing resistance, and good elasticity. Gradually become the dominant type of spiral cable instead of other types of spiral cable on the market.
