What should I do if the cable is wet in the rainy weather?

The delicate plum rain is scattered at will, the clouds are dense, every year, the plum rain comes on time, every year, it is inseparable from the ultimate products and services
provided by Far East Cable.
In rainy weather, indoor and outdoor humidity, how to avoid cable dampness? The editor has sorted it out for you, pack it and take it away~

1 There is a trick to keep the cable away from moisture

First of all, the quality of the cable should be strictly controlled, and when purchasing the cable, we must choose a manufacturer with excellent quality and strive to choose high-quality products
.

Secondly, to ensure that the cable head is well sealed, for the cable end that has been sawn, it must be sealed with plastic, and try to use a special sealing sleeve for the cable to prevent moisture from penetrating
.

After the cable is laid, the cable head is made in time, and if there are conditions, before making the cable joint, use a hair dryer to blow it out to drive out the water vapor, because of the conditions can not be made immediately, the cable head is sealed and wrapped and placed
in the air.

Of course, it is also necessary to improve the technical quality of the construction personnel, and it is required to be careful and careful, and when laying the cable, it is necessary to clean up the semi-conductive layer, and try to avoid damage to the main insulation, and finally the main insulation surface must be polished smooth
.

Finally, after the cable laying is completed, the cable head should be made to ensure a DC withstand voltage leakage test
.
Medium voltage cable, is DC withstand voltage test, low voltage cable can be insulated resistance with 1kV megohmmeter, at least greater than 5MΩ, to ensure that everything is qualified before putting into operation
.

2 Far East Cable accompanies you

As a leading enterprise in the wire and cable industry for 36 years, Far East Horizon deeply integrates the concept of standardization and institutionalization into corporate culture and production and operation, and is committed to creating the ultimate products and services
for customers.
In the production and research and development of cables, we strive for safety and environmental protection, and in the current "love, truth, goodness, beauty" series of cloth wire products, the "love" series of cloth wire focuses on strengthening "safety" and "durability"
.

01 Outstanding moisture-proof performance, water absorption rate ≤1mg/cm², with anti-aging, moisture-proof, high flame retardant, anti-overload and other properties, durable enough
.

02 The use of high-purity and high-quality electrical copper, with excellent electrical properties and super overload resistance
.

03 The insulation adopts the patented formula of high-voltage grade polyolefin inner insulation and high flame retardant polyolefin outer insulation, double-layer protection, corresponding flame retardant performance through GB/T 19666-2019 single vertical combustion and bundle combustion class A experiment, short circuit temperature (5s) of 250 °C to further strengthen the safety attributes
.
In the official product description, the thermal life of "Love" series cloth wire under normal conditions can reach 70 years and above, in line with the EU RoHS directive, and is widely used in high-end home decoration, major projects, super high-rise buildings and other important occasions
.

Next, Xiaobian takes you to understand the damage of moisture to cables

Cable moisture or water ingress will cause the insulation resistance of the cable to decrease, which is an important hidden danger
that causes accidents in cable lines.
The new production of the whole cable in the factory, both ends will be sealed with a plastic sealing sleeve, in the specific construction process will be used due to the actual situation, the remaining part will be simply wrapped with plastic sheeting a break, usually placed in the open air and sealed badly, over time water vapor will penetrate into the cable
.

When laying cables, sometimes because of the weather, cable trenches will accumulate a lot of water, cables will also be immersed in water, at this time plastic cloth wrapping is not tight or damaged will make water into the cable, especially like water plants and other factories located by the river, due to the factory area set up clear pools, drainage ditches and other production facilities with a larger water surface, high humidity is easy to make the cable damp.

In addition, when the cable is laid, it is limited by the on-site construction conditions, and the exposed cable head is not treated, resulting in long-term exposure to the air, and some are even immersed in water, and water vapor will enter the cable
in large quantities.
During the normal operation of the cable, if a breakdown and other failures occur for some reason, the water in the cable trench will enter the inside of the cable along the fault point, and it is not uncommon
for cables to be damaged or broken down due to various human factors in civil construction, especially at construction sites using large construction machinery.

Having said all this, I hope that the content of this issue can be helpful to everyone Oh, look forward to your message suggestions, the next issue will not be dispersed~ (Xi Yanmei)
