What is the difference between RVVP and RVSP cables

In the field of wire and cable, RVVP and RVSP cables are two common products. They differ in structure, shielding mode and application field.

First, RVVP cable introduction

1.1 The English name of the RVVP Cable is RVVP Cable, where the meaning of each letter is as follows:

R: Representative

V: PVC (Polyvinyl Chloride)

VP: Insulation and Sheath

1.2 Structure: The structure of RVVP cable includes:

Copper core: as a conductor of current transmission, providing a transmission channel for electrical signals.

Polyvinyl chloride (PVC) insulation layer: used to insulate conductors to prevent current leakage or short circuit.

Copper wire braided shield layer: covered in the insulation layer, used to shield external interference, protect the stability of signal transmission.

External PVC sheath: As the outermost layer of protection, protecting the entire cable from physical damage and environmental impacts.

1.3 Materials: The main materials include:

Copper: As a conductor material for current transmission, it has good electrical conductivity and mechanical strength.

PVC: Used as an insulating layer and sheathing material, with good insulation performance and durability.

1.4 Features:

Good anti-interference: copper wire braided shielding layer can effectively block external electromagnetic interference and ensure the stability of signal transmission.

Flexibility and easy installation: RVVP cables are flexible and flexible due to their soft material, making them easy to install and wire.

A wide range of applications: RVVP cable is suitable for communication, audio, broadcast, sound systems, anti-theft alarm systems, automation devices and other fields, especially for the need for high-quality signal transmission and anti-interference occasions.

1.5 Main application fields:

Communication system: such as telephone lines, network lines, etc.

Home audio system: such as speakers, audio cable, etc.

Security system: such as surveillance cameras, alarm equipment, etc.

Automation devices: such as robots, automated production lines, etc.

1.6 Technical Parameters:

Operating temperature: general type does not exceed 70℃, special type can reach 105℃.

Rated voltage: 450/750V.

Second, RVSP cable introduction

RVSP cable is a copper core conductor polyvinyl chloride insulated stranded shielded flexible wire, commonly used for cable connection of specific electronic devices and automation devices.

2.1 The English name of the RVSP Cable is RVSP Cable, where the meaning of each letter is as follows:

R: Representative

V: PVC (Polyvinyl Chloride)

S: I'm Twisted.

P: Shielded (shielded)

2.2 Structure and material: RVSP cable is mainly composed of copper core conductor, polyvinyl chloride (PVC) insulation layer, stranded conductor, copper wire braided shielding layer and external PVC sheath. The stranded conductor can effectively reduce electromagnetic interference and improve the stability of signal transmission, while the copper wire braided shield can further protect the signal from external interference.

2.3 Features:

Good anti-interference: RVSP cable adopts stranded shield design, which can effectively reduce electromagnetic interference and ensure the stability of signal transmission, especially suitable for occasions with high signal quality requirements.

Wide applicability: RVSP cable is suitable for the cable connection of electronic equipment and automation devices with rated AC voltage 300/300V and below, such as electrical appliances, meters, frequency converters, sensors, etc.

Strong flexibility: RVSP cable is made of soft material, has good flexibility and bending, easy to install and wire, suitable for a variety of complex wiring environment.

2.4 Main application areas:

Cable connections for electronic devices

Cable connection of automation device

Signal transmission of frequency converters, sensors and other electronic equipment

2.5 Technical Parameters:

Operating temperature: Generally speaking, the maximum operating temperature of conventional RVSP cables is 105°C. However, according to different insulation grades and models, its temperature resistance is also different:

Ordinary XLPE insulated RVSP cable, maximum operating temperature 105℃.

High temperature XLPE insulated RVSP cable with maximum operating temperature up to 130℃.

Special high temperature XLPE insulated RVSP cable, the maximum operating temperature can even reach 150℃.

Rated voltage: 300/300V.

Third, RVVP and RVSP cable difference and comparison

3.1 Insulation material:

RVVP cable uses PVC as insulation material,PVC heat resistance is poor, long-term operating temperature should not exceed 70°C.

RVSP cable uses XLPE as insulation material,XLPE heat resistance is better than PVC, conventional type can withstand temperature 105°C, special models can even reach 150°C.

For example, in the high-temperature workshop of a steel plant, the ambient temperature may be above 80°C for a long time, and if the use of RVVP cables will face the risk of aging or foaming insulation, RVSP cables can cope with this high temperature environment.

3.2 Application difference:

RVVP cables are mainly used for fixed laying, such as cabling in equipment rooms and offices, and are not suitable for outdoor or humid environments.

RVSP cable has a wider range of use, including outdoor overhead, pipe gallery, underground buried and other harsh environments.

3.3 Other differences:

RVSP cable flame retardant better, a single cable flame retardant grade up to FV1. The flame retardant grade of RVVP cable is generally ST1.

RVSP cable has good ultraviolet aging performance, suitable for long-term outdoor use; Long-term exposure of RVVP cables to ultraviolet rays will accelerate aging.

Forth, Conclusion

To sum up, there are obvious differences between RVVP cables and RVSP cables in terms of structure, materials and application fields. When choosing, it is necessary to comprehensively consider the specific use environment and requirements, and weigh their advantages and disadvantages to ensure that the most appropriate product is selected.

Specifically, for general indoor fixed laying environment, such as computer rooms, offices, etc.,RVVP cable is economical, easy to install, and can be used as the first choice. However, it should be noted that RVVP cables should not work in high temperature, humidity or ultraviolet direct exposure for a long time.

For harsh outdoor environments, such as direct sunlight, large temperature differences, wet and rainy, or some special high temperature, fire protection requirements of the occasion, it is strongly recommended to use more excellent performance RVSP cable. Despite the high price of RVSP cables, their excellent heat resistance, moisture resistance, flame retardant and aging resistance can significantly extend the service life and be economical in the long run.
