KVVP cable is a type of shielded control cable, where "K" represents the control cable, "VV" represents polyvinyl chloride insulation and sheath, and "P" represents the shielding layer. This type of cable is designed and manufactured with a shielding layer added to reduce the impact of electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring stable signal transmission.
KVVP cables are widely used in industrial automation, power systems, construction, transportation and other fields, as an important component of control, signal transmission, and power lines.

Products characteristic

Shielding layer: The cable contains one or more layers of shielding layer inside, usually woven or wrapped with copper wire or copper tape, which can effectively prevent interference from electromagnetic fields and external signals, ensuring the accuracy and stability of signal transmission.
Conductor: usually high-purity electrolytic copper with good conductivity.
Insulation layer: Made of polyvinyl chloride (PVC) material, this material has good electrical properties and mechanical strength, which can effectively isolate the conductor from the external environment and prevent current leakage.
Sheath: PVC material is also used to protect the internal structure of the cable and increase its durability and wear resistance.
Good anti-interference performance: Due to the presence of a shielding layer, KVVP cables can resist electromagnetic interference from external environments and are suitable for situations that require high reliability signal transmission.
Widely applicable: KVVP cables are commonly used in industrial automation, power systems, computer networks, monitoring systems, and other fields, especially in environments with high requirements for signal transmission quality.

FAQ

Q1: Are you a factory or a trader?
A1: We are a professional wire and cable factory with significant advantages in price and quality.

Q2: What are the main characteristics of KVVP cables?
A2: KVVP cable is a type of shielded control cable, characterized by a shielding layer that can effectively reduce the impact of electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring stable signal transmission. In addition, it also has polyvinyl chloride (PVC) insulation and sheath, providing good electrical performance and mechanical strength.

Q3: What is the function of the shielding layer of KVVP cables?
A3: The shielding layer of KVVP cable is made of copper wire braided or wrapped with copper tape. Its main function is to reduce the interference of external electromagnetic fields on the internal signal of the cable, while preventing the internal signal of the cable from radiating outward, thereby ensuring the stability and reliability of the signal.

Q4: What are the grounding methods for KVVP cables?
A4: There are usually two grounding methods for KVVP cables: one end grounding and the other end grounding. When one end is grounded, the shielding layer voltage is zero, which can significantly reduce the static induced voltage. However, when the induced impulse is high, the non grounded end may experience a higher transient voltage. When both ends are grounded, when the cable is surrounded by the magnetic flux generated by the transient current of the busbar, the shielding layer will induce shielding current to offset the impact of the magnetic flux generated by the transient current of the busbar on the cable core. However, it should be noted that when there is a short circuit current or lightning current on the grounding grid, it may cause additional surge or interference voltage.
