The use of cables has become commonplace in today's live production activities. With the development of science and technology and the change in demand, the types of cables are also constantly enriched.
And in the mixed cable market, some unscrupulous manufacturers will put unqualified cable products into the market. Unqualified cables not only bring a certain degree of difficulty to the procurement of enterprises, but also the normal operation of the power system buried security risks.
Today ZMS cable editor to give you a little science.
The logo is the main way to use wire and cable to identify the basic information about the product.
According to the standard provisions of the logo is the main content: product type, specification, standard number, factory name, origin, etc. in a certainly marked spacing.
When the logo is not qualified, it will cause the construction personnel to identify the wrong, serious will cause electrical accidents.
The main problem of structural dimensions is the sheath thickness and insulation thickness.
When the sheath and insulation thickness of the cable is not up to standard, it will lead to wire and cable electrical strength will be seriously reduced.
Resulting in shortening the service life of the wire and cable, and will seriously lead to wire and cable penetration.
The insulation layer or sheath does not play a normal protective role so electrical short circuits and fire and other phenomena.
Insulation sheath aging before the tensile strength and elongation failed to directly and greatly shorten the working life of wire and cable.
And in construction or in a long time and high-temperature environment, the insulator is very easy to fracture, resulting in exposed live conductors, and the risk of electric shock short circuit.
The main reason for its failure is the use of recycled material production to reduce product costs, the second is not qualified to produce small businesses.
Conductor resistance is mainly to assess the conductor material of wire and cable and whether the cross-section is in line with the important indicators.
When the conductor resistance exceeds the standard, it increases the loss of current through the line, intensifying the heating of wire and cable.
Conductor resistance failure is mainly due to enterprises reducing costs, which will account for 80% of the cost of raw materials, and copper shrinkage.
And either reduce the cross-sectional area of the conductor or the use of recycled copper containing impurities too high.
This results in wire and cable conductor resistance seriously exceeding the standard, in addition to the use of the process being prone to fire, but also accelerating the aging of the insulation layer wrapped in wire outside.
Wire and cable are often used in our daily life of electrical equipment, we usually neglect to do routine maintenance on them.
However, if we can use and protect them properly, their life span can be extended within reasonable limits. The following is a brief description of how to maintain cables daily.
Wire and cable are extremely sensitive to moisture, so keeping them dry is key to maintaining their usefulness.
If wire and cable are exposed to moisture for a long time, it can easily cause dielectric damage, leading to electrical failure or equipment damage.
To keep dry, try laying waterproof material around the wire and cable or using enclosed wire and cable.
Frequent current overloads can lead to a shortened service life of wire and cable because overloads increase the wear and tear of wire and cable.
Overloads can also cause the temperature of the wire and cable to rise, which increases the risk of shortening the life of the wire and cable.
Therefore, ensuring the proper selection of wire and cable assemblies, proper load control, and avoiding overloads can properly extend the service life of wire and cable.
Regular inspection of wire and cable is essential to ensure its proper operation.
In addition to regularly inspecting wire and cable for physical damage, wire, and cable connectors and contactors should also be inspected.
If there is a break or poor contact, it should be replaced or repaired in time to avoid potential failure.
When wires and cables work continuously for a long time, their temperature will rise, thus shortening their service life.
Therefore, to let the wire and cable "rest", you can intermittently turn off electrical equipment, and let the wire and cable cool after use.
This intermittent use can reduce the maintenance and renewal costs of wire and cable.
Finally, choosing quality wire and cable is also key to extending the life of your cables.
Quality wire and cable usually have better electrical performance and longer service life, providing better protection for equipment.
Be careful not to save money by using wire and cable that is too cheap, as this may directly affect your equipment and safety.
In general, these methods above can effectively extend the life of wire and cable.
Finally, ZMS cables manufacturer would like to say that although these methods may seem simple, they can save a lot of money on equipment repairs and updates.
Therefore, proper use and protection of wire and cable are essential, as well as improving the life and safety of electrical equipment.
