Low Voltage Cable
- According to IEC 60502-1, GB
- XLPE Insulation, PVC and LSZH Sheath
- Approved by IEC, ISO, BV, SGS
- Large stock low voltage power cables with different sizes
- Related Voltage 0.6/1KV
What is the low voltage cable?
The cables below 0.6/1KV (included) are low-voltage cables. The difference is that the withstand voltage is different, insulation and sheath structure is also different. There are 0.3/0.5kv 0.45/0.75kv that is belonged to control cable. The low voltage is 0.6/1KV. The purpose of the low voltage power cable is to connect the conductor of low-voltage power and equipment. The ability to make the equipment get power through the cable to do work. There are also control cables, communication cables, signal cables, etc. all belong to low voltage cable.
How should low-voltage cables be selected?
(1) In the general environment we should be used aluminium cable but in complex and special buildings and places. We will choice outdoor low voltage cable.
(2)Underground cable, generally using SWA cable and STA cable.
(3)In the chemical corrosion should not use underground cable.
(4). In the same low voltage cable specifications, we need to choose the cable with a better appearance. The cable is marked with the manufacturer’s name, specification, and meter mark. The cable manufacturer can issue a test report of the cable. Compare more samples of the cable. ZW Cable can be your best choice.
Rules for wiring of low voltage cables
Low voltage cable insulation should be laid according to the project conditions, environmental characteristics, cable type and a number of factors, according to meet the operational reliability, ease of maintenance and technical, economic and reasonable.
2, The selection of the minimum distance of the cable should meet the following requirements.
a. should avoid mechanical external forces, overheating, corrosion and other hazards to the cable;
b.should be easy to lay and maintain;
c. should avoid construction sites or construction sites in the site plan;
d. should meet the safety conditions so that that minimum cable distance is the shortest.
e. The cable should not be used indoors with a protective layer that can easily burn.
The insulating material is used for low voltage cables
Low voltage cables are used polyvinyl chloride (PVC), polyethylene (PE) and cross-linked polyethylene (XLPE). PVC is still widely used in low-voltage cables with the advantages of convenient process, good comprehensive electromechanical performance, good flame retardant performance and low cost. Polyethylene is widely used in cable insulation and outdoor cable sheathing for its advantages of good electrical properties, good moisture resistance and cold resistance, while cross-linked polyethylene is widely used in medium and high voltage cable insulation for its excellent electrical and mechanical properties. Polypropylene is widely used in cable insulation and outdoor cable sheathing because of its superior electrical properties, good resistance to high temperature and oil resistance.
The sheath material is used for low voltage cables
Low voltage electrical cable has 3 sheath materials. The first one is 70 degree PVC, The Second one is flame retardant sheath, and the last one is low smoke and halogen-free sheath, which we usually also call LSZH cable. LSZH cable is more expensive, but larger projects use this material such as hospitals, subways and other large projects. This material will not have a smoke when the cable is on fire, which is why more and more people are using it now.
