With the vigorous development of new energy industry, New energy cable As a key component connecting power generation, transmission and consumption, its performance directly affects the safe and stable operation of the whole system. Among them, high compression resistance is one of the important properties that new energy cables must have, which is directly related to the service life and reliability of cables in complex environments.
1、 Why do new energy cables need high compression resistance?
Compared with traditional cables, new energy cables are faced with more stringent use environment, such as:
Complex and changeable environment: New energy projects are mostly built in remote areas, such as desert, gobi, sea, etc. These areas have harsh climate conditions, large temperature difference between day and night, strong ultraviolet radiation, and severe salt spray corrosion, which put forward higher requirements for the mechanical performance and weather resistance of cables.
Various laying methods: The laying methods of new energy cables include direct burial, pipe threading, overhead, etc. Different laying methods have different requirements on the compression resistance of cables. For example, directly buried cables need to bear soil pressure and mechanical damage, and overhead cables need to bear wind load and snow load.
Poor operating environment: During the operation of new energy cables, they are subject to current, voltage, temperature and other stresses for a long period of time, and are prone to aging, deformation, cracking and other problems, affecting the service life of cables.
Therefore, the new energy cable must have high compression resistance to cope with the complex and changeable use environment and ensure its long-term safe and stable operation.
II New energy cable manufacturer How to improve the pressure resistance of products?
In order to meet the demand for high compression resistance of new energy cables, manufacturers usually improve and optimize from the following aspects:
1. Material selection:
Conductor material: High purity oxygen free copper or aluminum alloy is used as conductor material to improve conductivity and mechanical strength.
Insulation material: High molecular materials such as cross-linked polyethylene (XLPE) and ethylene propylene rubber (EPR) are used as insulation layers to improve insulation and heat resistance.
Sheath material: PVC, PE, PUR and other materials are used as the sheath layer to improve the wear resistance, corrosion resistance and UV resistance.
2. Structural design:
Conductor structure: Compact stranding or profiled wire stranding structure is adopted to improve the filling coefficient and mechanical strength of conductors.
Insulation thickness: According to the voltage level and service environment, reasonably design the thickness of the insulation layer to improve the insulation performance and compressive strength.
Shield design: Copper tape shielding or copper wire braided shielding is adopted to improve the anti electromagnetic interference ability of the cable.
Armor layer design: Steel tape armouring or steel wire armouring is used to improve the compression resistance and mechanical strength of the cable.
3. Production process:
Strictly control the quality of raw materials: Strictly inspect the quality of raw materials to ensure that they meet the requirements of relevant standards.
Optimize production process parameters: Strictly control extrusion temperature, pressure, speed and other process parameters to ensure stable and reliable product performance.
Strengthen quality inspection: The finished cable shall be strictly tested for mechanical performance, electrical performance and environmental performance to ensure that the product meets the requirements of relevant standards.
3、 How to choose new energy cables with high compression resistance?
When selecting new energy cables, users need to select products with high pressure resistance according to the specific use environment and needs. Here are some suggestions:
Select famous brands: Well known brands usually have advanced technology, strict quality control system and perfect after-sales service, and the product quality is more guaranteed.
To view product certifications: Select products that have passed relevant certification, such as CCC certification, CE certification, UL certification, etc., to ensure that the products meet the requirements of relevant standards.
Focus on product parameters: Focus on parameters such as conductor cross-sectional area, insulation thickness, sheath thickness, armor layer type, etc. of the cable, and select products that meet the requirements of the use environment.
Consulting professionals: If in doubt, you can consult professional cable engineers or manufacturer's technicians for more professional advice.
4、 Summary
High compression resistance is one of the important properties that new energy cables must have, which is directly related to the service life and reliability of cables in complex environments. New energy cable manufacturers continuously improve the compression resistance of their products by optimizing material selection, structural design and production process to meet the needs of new energy industry development. When selecting new energy cables, users need to select products with high compression resistance according to the specific use environment and needs to ensure their long-term safe and stable operation.
