The cable tray vendors planner should be aware of the specifications to ensure that the volume occupied by the cable meets the requirements, generally 40% better

With the development of society, the construction industry is developing very rapidly, and it is very necessary for the construction industry to use electricity.
The application of cable tray vendors has also been well developed, and it is used more and more frequently in reality, and it also brings great help to people's life.
However, there are still many problems to be paid attention to in how to use the bridge.
Let's talk about how to use stainless steel bridge correctly. Let's take a look at it.
1.The bridge planner should be aware of the specifications to ensure that the volume occupied by the cable meets the requirements, generally 40% better.
Try not to exceed the conventional density, so as not to accelerate the aging of cable insulation, otherwise the demand will increase cable and investment.
2.The cables and wires on the bridge can not be put in the same slot.
Reason: the allowable temperature of the two types of wires is different, the wire insulation is thin, and it is easy to be broken by the cable.
The mechanical strength of the wire is not good, it will break the cable.
3.Different types of cables should not be laid in the same slot, mainly because of the inconsistent working temperature, such as 65 degrees of VV series and 90 degrees of YJY series.
If laid in the same slot, the low temperature resistant cable will accelerate the insulation aging.
4.The capacity of the cable laid in the slot should be considered according to the number of cables in the same slot and the temperature of the laying environment.
In general, 60% to 80% of the extra capacity of the cable should be considered, and 50% to 70% of the poor heat dissipation of plastic slots can be considered.
5.Because of its special structure (fireproof cotton and fireproof board are added inside), the internal space of fireproof bridge is smaller than that of ordinary bridge, so we should pay attention to the volume ratio of cable when choosing.
Due to poor heat dissipation conditions, the flow carried by the cable can be regarded as 40% to 60% of the additional flow carried by the cable.
The constant weight is heavier than the general bridge frame, so the fixed support and hanger can not be set up according to the standard distance in the steel cable tray vendors planning code, and the density should be increased.
It is suggested that the distance of 1-1.5m should be selected according to the size of the proposed bridge.
These are five points for attention in the correct use of stainless steel bridges.
Although the development of the bridge plays a vital role in our life, how to use the bridge correctly and the matters needing attention.
This is a problem that managers should pay attention to.
