CSA C68.10 is a standard issued by the Canadian Standards Association for shielded power cables for commercial and industrial applications with a rated voltage between 5-46 kV. The standard includes the following:
1.Cable size and construction.
2.The material and properties of the cable.
3.Cable test methods and requirements.
4.Installation and use of cables.
Shielded cables are used in a wide range of applications and are commonly found in power supplies in commercial and industrial areas. Its shielding structure can effectively reduce external interference and electromagnetic radiation, and improve the stability and reliability of the cable.
Features
Shielded power cables specified by CSA C68.10 have the following advantages
1. The shielding structure can effectively reduce external interference and electromagnetic radiation, and improve the stability and reliability of the cable.
2. The cables are made of environmentally friendly, low-smoke, and halogen-free new materials, which have good weather resistance and corrosion resistance, and can adapt to different environmental requirements.
3. Manufactured and tested according to CSA C68.10 standard to ensure that the cables meet international standards with good quality and reliability.
4. It is specially designed for power supply applications in commercial and industrial fields, and can meet the high requirements of these application scenarios for power supply.
In summary, the shielded power cables specified by CSA C68.10 have the advantages of anti-interference, anti-radiation, good weather resistance, and reliable quality, which can ensure the safety and stability of power supply in commercial and industrial fields.
Application
CSA C68.10 is a shielded power cable standard for commercial and industrial applications issued by the Canadian Standards Association, mainly applicable to occasions with rated voltages between 5-46 kV. The main function of the shielded cable is to reduce electromagnetic interference and electromagnetic radiation, and improve the stability and reliability of the cable.
CSA C68.10 is suitable for various power supply applications in commercial and industrial fields, such as power distribution systems, manufacturing plants, large buildings, hospitals, airports, subways, etc. These application scenarios require a stable power supply, and shielded cables can effectively reduce external electromagnetic interference, thereby ensuring the safety and stability of power supply.
At the same time, the shielded cable also has good weather resistance and corrosion resistance, and can adapt to different environmental requirements. In the design and construction of power systems, choosing shielded cables that meet the CSA C68.10 standard can improve system reliability and stability and reduce the risk of system failure.
Construction
The structure of shielded power cables specified by CSA C68.10 generally includes the following parts
- Conductor
Generally it mades of copper or aluminum, as the transmission medium of the cable. - Insulation layer
Covering the outside of the conductor, it is used to isolate the conductor and the shielding layer to avoid current leakage and interference. - Shielding layer
Outside the insulating layer, wrap the conductor and the insulating layer to reduce electromagnetic interference and electromagnetic radiation. - Sheath layer
Covering the outside of the shielding layer to protect the cable from mechanical damage and external environment.
In summary, the shielded power cable structure specified in CSA C68.10 generally consists of a conductor, an insulating layer, a shielding layer and a sheath layer, among which the shielding layer is a key part, and can be shielded by a metal shielding layer or an insulating layer.
