The advantages of LSZH cable

LSZH cable is a new type of environmentally friendly cable, compared with ordinary cables, has obvious advantages. This article will discuss the advantages and disadvantages of LSZH cables and ordinary cables, development trends and other aspects.

First, the benefits of LSZH cable

1. Environmental protection: LSZH cable is made of halogen-free materials, does not contain lead, cadmium and other harmful substances, does not produce toxic fumes when burning, harmless to the environment and human health. While the ordinary cable will produce a lot of harmful gases and smoke when burning, seriously polluting the environment.

2. Safety: The insulating material of LSZH cables has good flame retardant properties, which is not easy to burn in case of fire and can effectively reduce the speed of fire spread. In addition, the smoke density of LSZH cable is low, which is conducive to the evacuation and rescue. Ordinary cables are easy to burn in a fire, exacerbating the spread of fire, posing a threat to the safety of personnel.

3. Corrosion resistance: LSZH cable sheath material has a strong corrosion resistance, suitable for harsh environments. Ordinary cable sheath material in the corrosive environment is easy to aging, damage, resulting in cable failure.

4. Transmission performance: LSZH cable conductor material is generally oxygen-free copper, excellent electrical conductivity, high transmission efficiency. Common cable conductor materials may contain impurities, conductivity is relatively poor.

5. Lifespan: LSZH cable insulation materials and sheath materials have better aging resistance, longer service life. Ordinary cables are susceptible to environmental influences during long-term use and have a relatively short service life.

Second, the disadvantages of LSZH cable

1. Cost: The production cost of LSZH cables is higher, resulting in a more expensive selling price than ordinary cables. This may be the main reason to restrict the popularity of LSZH cables. 2.

2. Difficulty in construction: The hardness of LNH cables is greater, and special cutting and bending tools may be needed during construction. The construction of ordinary cables is easier.

3. Compatibility: Low smoke halogen free cable has poor compatibility with some traditional equipment and accessories, which may require additional investment for transformation.

Third, the development trend

1. Policy promotion: With China's emphasis on environmental protection and safety, the relevant policies continue to improve, LSZH cables in public places, important facilities and other areas of application will be vigorously promoted.

2. technological progress: with the continuous development of materials science and manufacturing technology, LSZH cable production costs are expected to be further reduced, the performance continues to improve, market competitiveness.

3. Market demand: With the improvement of people's awareness of environmental protection, the demand for LSZH cables is gradually increasing, and the market outlook is broad.

4. Industry consolidation: LSZH cable market will gradually phase out the technological backwardness, unstable quality of enterprises, high-quality enterprises will stand out, market share continues to increase.

In short, low-smoke halogen-free cable has obvious advantages, although there are certain shortcomings, but with the policy to promote, technological advances and market demand continues to improve, low-smoke halogen-free cable in China's development prospects are very broad. In the future, low-smoke halogen-free cables are expected to gradually replace ordinary cables and become the mainstream products in the cable market.

The installation of LSZH cable need to pay attention to what issues

The installation of LSZH cables requires attention to the following issues to ensure the safe, reliable and efficient operation of the cable system:

1. Check before laying the cable:

- Check whether the cable type and specification meet the design requirements.

- Confirm that the appearance of the cable is undamaged and that the insulation and sheath are intact.

- Check whether the insulation resistance of the cable meets the standard.

2. Laying environment:

- Avoid laying cables in humid, high temperature, oily or chemically corrosive substances.

- Ensure that the laying path is smooth and free of sharp objects to avoid damage to the cable.

3. Bending radius:

- The bending radius of low-smoke halogen-free cables should be greater than the specified minimum bending radius to avoid damage to the cable insulation.

4. Tension control:

- Tension should be controlled during laying to avoid exceeding the maximum allowable tension of the cable to avoid damaging the cable structure.

5. Fixing and supporting:

- Cables shall be properly fixed and supported during laying to avoid sagging or damage due to gravity or external factors.

- Set up fixing points at certain distances at turning points and straight sections.

6. Fabrication of joints and terminations:

- Fabrication of joints and terminations should be carried out by specialised personnel to ensure the quality and performance of the joints.

- Strictly follow the manufacturer's instructions and standard workmanship.

7. Insulation Treatment:

- The joints and terminations should be well insulated to prevent leakage and short circuit.

8. Grounding:

- For systems requiring grounding, ensure that the grounding is reliable and the grounding resistance meets the specified requirements.

9. Protective measures:

- For cable parts that may be subject to mechanical damage, appropriate protective measures should be taken, such as pipe threading, the use of cable bridges and so on.

10. Marking and recording:

- After cable laying is completed, it should be clearly labelled, including information such as cable type, specification and date of laying.

- Record the cable laying path, length, joint location, etc., to facilitate future maintenance and management.

11. Test:

- Upon completion of laying, insulation tests should be carried out on the cables to ensure that there are no short-circuits and ground faults.

- If necessary, carry out electrical performance tests of the cable, such as DC resistance test, insulation resistance test, etc..

12. Compliance with norms:

- Relevant national and industry standards and codes should be strictly observed during installation.

The above precautions can ensure the installation quality of LSZH cables and reduce the faults and safety hazards caused by improper installation.
