gui chao cable news: home appliance cable how to extend the service life-非凡电子娱乐

we all know that anything is the service life of the cable is no exception, the power of copper wire in the design life of 20~30 years, the telephone line design life of 8 years, the cable design life of 10 years, is not to say that in this period of wire and cable will be bad, can be used as a reminder.

so how to prolong the service life of the cable?

heat - the temperature of the cable in the metal pipe or wire slot is very high, a lot of polymerization data in this temperature will decrease the service life

water - in the local area network of twisted pair cable moisture will increase the cable capacitance, thereby reducing the impedance and lead to near end crosstalk

mechanical damage (amendment) - optical cable repair is very valuable, at the end of each inter - point at least two times the termination

grounding - if the cable's shield is grounded, it is necessary to comply with the relevant specifications.

the total length of the route (not only refers to the floor) - between the building of the outdoor area of the lan cable, the total length of 90 meters within the constraints. on 100mps or 1000mbps networks, the laying interval should not exceed this limit. such as the laying of the interval between 100 meters to 300 meters, the cable should be selected.

how to place outdoor cable

1 under the eaves. the cable can be used only when the cable is not directly exposed to the sunlight or the super high temperature.

2 exterior wall. to prevent direct sunlight and man-made damage to the wall.

3 in a pipe (plastic or metal). such as in the pipeline, pay attention to the damage of plastic pipe and metal pipe heat conduction.

4 floating / overhead cable. consider cable sag and pressure. what kind of binding method is planned to use the cable is not directly illuminated by the sun.

5 directly in the underground cable trench laying, this environment is the smallest control. cable trench device should be regularly dry or wet degree of view.

6 underground pipeline. in order to facilitate the subsequent promotion, cable replacement and the appearance of pressure and the surrounding environment barrier, auxiliary pipeline phase barrier, auxiliary pipeline is a better way. but don't hope that the pipeline will permanently dry, which will affect the selection of cable varieties.
