Overview of cvv cable

What is cvv cable?

Cvv stands for CU/PVC/PVC, a type of electrical cable designed with a core made of multiple strands of pure soft copper, insulated with PVC material, and covered with PVC sheath. Widely used in civil power grid systems, the characteristic of cvv is its ability to transmit stable voltage for low-voltage electrical lines. Cvv cables come in various types. Some common types of CVV cables include:

  • Cvv 2-core cable.
  • Cvv 3-core cable.
  • Cvv 4-core cable.
  • Cvv 3+1; 4+1 cable.

Structure of cvv cable

CVV cables are formed by combining multiple twisted soft copper conductors, insulation, and PVC sheath:

  • Conductor core made of pure copper.
  • Insulation using PVC material.
  • Filler layer may be made of PP wound with PET or PVC.
  • Outer sheath is made of PVC.

  • JZ-500 cable

Outstanding features of cvv cable

The distinctive structure of the cvv cable endows it with several advantages, including:

  • Stable performance: Cvv cable is designed with a conductor core made of pure copper, ensuring high electrical conductivity and stable signal quality.
  • Durability: The insulation layer made of PVC material protects the conductor core from the influence of external factors such as moisture and temperature, ensuring the cable's safety during use. Additionally, the high-quality PVC outer sheath enhances flexibility and ensures the cable's durability in harsh environments.
  • Versatility: Cvv electrical cables can meet various requirements and are widely used in civilian power transmission systems, low voltage, medium voltage, and industrial applications. Moreover, the flexible design of cvv cable facilitates easy installation and maintenance in electrical systems, reducing costs and deployment time.

Overview of cxv cable

What is cxv cable? Structure of cxv cable

Cxv cable is a specialized type of cable for low-voltage electrical systems with the capability to transmit voltage levels of 0.6/1kV. The structure of cxv cable includes a conductor core made of multiple strands of high-purity, soft-grade copper (class 2), insulation made of XLPE, and an outer sheath made of PVC. The components of cxv cable structure are as follows:

  • Conductor core: The cable's conductor core utilizes high-purity solid copper, enhancing its conductivity and minimizing energy loss.
  • Insulation layer: The insulation layer of cxv cable is made from XLPE material, providing excellent heat resistance and high dielectric strength, ensuring safe insulation.
  • Filler layer: The filler layer can be made from PVC or PP wrapped with PET.
  • Outer sheath: The outer sheath of cxv cable is made from high-quality PVC, capable of withstanding high temperatures and protecting the cable from environmental influences.

Outstanding features of cxv cable

Prominent advantages of the cxv cable:

  • Excellent conductivity: The conductor core of the cxv cable is manufactured from high-purity copper, providing optimal conductivity. This helps maintain stable performance during electrical transmission.
  • Heat resistance: The XLPE insulation layer not only offers high heat resistance but also maintains excellent dielectric strength, ensuring the safety and stability of the system.
  • Fire resistance: The PVC outer sheath of the cxv cable possesses effective fire resistance, enhancing safety in the operating environment.
