The installation of cable branch box and application

As town construction pace is accelerated, corridor of program of 10 KV circuitry and contradiction of construction of town planning development are added increasingly drama. Expand demand to get used to a society, realize safe, stable, reliable power supply. Act on " typical design, optimize move, on the safe side " principle, street to county main force, a sector of an area executes cable region power supply, use cable branch box to regard the important form a complete set of distribution as equipment, optimized cable road network, achieved distribution of much loop branch, namely beautification city, rose to run dependability and security again, success application received in full city county.

The technical program of box of 1 cable branch

The structure of box of 1.1 cable branch, characteristic and function

Completely airtight, complete defend, fight defilement, fight corrode, satisfy outdoors and round-the-clock Hou to run a condition, can get used to different working environment.

Cable branch box belongs to a ground type casing, volume is minor, cover an area of an area small also, if some covers an area of an area to be 0.65 M2, those who lead SF6 switch cover an area of an area to be 1.45 M2 only; The shell is beautiful, won't cause to town appearance destroy.

The conductor inside branch box joins use crimp means, installation is convenient, line of pass in and out is agile, there can be 6 ～ at most in applying line of 8 branch pass in and out, can realize village multichannel power transmission, for thorough bear center, shorten power supply radius, reduced line caustic to provide technical safeguard. At the same time cable branch box can deserve to take balata of power source indicator, breakdown indicator, silicon to be isolated from completely insert switch of lock of lightning arrester, rigid programmed control, ground connection to wait, ensure run the safety that defends management.

Cooperate power supply of type of net of cable network annulus, can configure switch of the annulus net such as SF6 bear, affecting advocate below the condition that the net runs, satisfy service call of local power cut, realize limits of overhaul of district power failure, contractible power cut. At the same time box of branch of annulus net cable can realize annulus net power supply, lay next foundations for the structural adjustment of network of 10 KV route henceforth.

The installation of box of 1.2 cable branch is used and note

The breed of box of branch of outdoors cable of 10 KV of our country production is at present various, accordingly, the installation construction of box of branch of 10 KV cable becomes very important. Cable branch box and the operation method that cable connect installs join process are accurate, end installation craft is familiar, of component of interior of cable branch box and combination of cable connect component early or late order, whether to offer installation standard manual to undertake operating waiting a moment according to manufacturer form a complete set, the service life that will affect cable branch box directly and move normally.
