A brief analysis of the problems of the outdoor weak electrical engincurrent technical and investment constraints,
In fact, the weak current cable is still a lot of, and each subsystem is in each pass
There are more than one cable in the losing direction, and there are quite a few
There are a dozen or even dozens in a transmission direction
Cable, these cables can be divided into copper core telephone cable, optical cable, video
And radio frequency coaxial cable, shielded control cable and all kinds of armored cable.
2. 2 underground pipelines
The general residential park underground has water pipes, high pressure and low pressure fire
Water pipes, water pipes, sewage pipes, high-voltage cables, 380 volt power cables,
Lighting street lamp cable, heating and air conditioning hot water (steam) tube and cold water
In addition, these pipes belong to the city Speech, radio and television (cable TV), power supply, water supply, gas and other different cities
The political department needs to be professional with the relevant management departments and their subordinates
The working unit is well coordinated and coordinated.
For the subsystems of the weak current, considering the application
The damage to the cable and the resulting liability is not clear
The reason for this is the cable of the weak current system which belongs to the low level
Cannot be laid in the same weak current system. This is the case
It is bad for the construction of the smart community, and it is not suitable for the current intelligence.
The situation of informat ionization and networked development, so the weak current system (broadcast
Cables should be laid out in the same system. Low electricity
The transmission cable of weak current signal is required to effectively prevent the wiring design
The introduction and interference of the anti-high potential is the requirement of the weak current system
A secure system. High pot
