RVVP cable, full name is copper core PVC insulated shielded PVC sheathed flexible cable, is a kind of cable widely used in a variety of occasions where anti-interference is required.
I. Product Characteristics
1.Conductor material:
RVVP cable usually adopts multi-stranded stranded copper conductor, which has good electrical conductivity and flexibility.This conductor structure not only improves the electrical performance of the cable, but also enhances its mechanical strength and bending resistance.
2.Insulation:
The insulation layer is made of high-quality polyvinyl chloride (PVC) material, which has good electrical insulation properties and chemical resistance.The PVC material also effectively prevents the intrusion of water and moisture and protects the internal conductors of the cable from damage.
3.Shield structure:
The shielding layer of RVVP cable consists of aluminum foil covering and tinned copper wire braided mesh, with a braiding density of more than 85%, which can effectively block external electromagnetic interference.This kind of shielding structure is especially suitable for the occasions with harsh electromagnetic environment, such as industrial automation control system, burglar alarm system, etc.
4.Sheath material:
The sheath is made of flexible PVC material, which can be made into flame retardant, low smoke non-halogen, fire-resistant and other types according to demand.This kind of sheath not only increases the durability of the cable, but also reduces the generation of toxic gases in the event of fire and improves safety.
5.Use temperature range:
The normal operating temperature of RVVP cables does not exceed 70°C. The operating temperature range is -30°C to +70°C for fixed installations and -5°C to +70°C for mobile installations.This wide range of temperature adaptability allows RVVP cables to work stably in a variety of environments.
6.Bending radius:
The permissible minimum bending radius of RVVP cables is not less than 5 times the outer diameter of the cable indoors and not less than 10 times outdoors.This design makes the cable more flexible during installation and use, and facilitates wiring and connection.
7.Flame retardant characteristics:
RVVP cables comply with the flame retardant standard of IEC 60332.1, which can slow down the spread of fire in case of fire and protect the equipment and personnel. The flame retardant properties are categorized into four grades: A, B, C and D, among which grade A has the best flame retardant properties.
6.Fire-fighting system:
II. Application Scenarios
1.Communication system:
RVVP cable is widely used in communication system for transmitting voice, data and video signals.Its good shielding performance can effectively prevent external electromagnetic interference and ensure the stability and reliability of signal transmission.
2.Audio and broadcasting system:
In audio and broadcasting systems, RVVP cables are used to connect audio equipment and broadcasting equipment to ensure high quality transmission of audio signals. Its flexibility and shielding performance make installation and maintenance more convenient, while reducing signal loss.
3.Burglar alarm systems:
RVVP cables are commonly used in burglar alarm systems to connect various detectors and alarm devices. Its anti-interference ability and durability enable the system to operate stably in complex environments.
4.Intelligent automation system:
In intelligent automation systems, RVVP cables are used to connect control devices and actuators to realize the automation control of the system.Its good electrical performance and shielding effect ensure the efficient operation of the system.
5.Automatic Meter Reading System:
RVVP cables are also used in automatic meter reading system to connect electricity meter and data collection equipment to realize remote meter reading function.Its stable signal transmission performance and anti-interference ability make the meter reading data more accurate and reliable.
6.Fire-fighting system:
In fire protection system, RVVP cable is used to connect fire detectors and alarm devices to ensure timely alarm when fire occurs.Its flame-retardant properties can slow down the spread of fire when it occurs and buy time for people to evacuate.
To summarize, RVVP cable has become an indispensable choice in many fields with its excellent anti-interference performance, diverse shielding structure, wide temperature adaptability and good flame retardant properties. Whether in complex industrial environments or communication systems with high requirements for signal transmission, RVVP cables provide stable and reliable solutions.
