Description
Technical field
The utility model is related to draw the lower technology reliably blocked to optical cable using 704 silica gel under high and low temperature environment, tool
Body is related to a kind of optical cable and draws lower waterproof plugging device.
Background technology
To have that transmission frequency bandwidth, capacity are big, loss is low, anti-interference etc. a series of for fiber optic communication a little, obtain in recent years fast
Speed development.So far, China has been completed one based on optical cable, it is supplemented by microwave, satellite, covering it is national, technologically advanced,
The network foundation platform of large capacity.Fiber optic communication is also widely used and develops in electric device, and logical as electric power
Primary communication mode in T unit.The medium that optical cable is transmitted as electric power signal assumes responsibility for protection, scheduling number between each substation
According to the transmission of the important services such as net, security reliability directly affects effective transmission of all kinds of power communication signals.Guide light
Coupling part of the cable as line side and transformer substation communication computer room, the links such as design, construction, O＆M have particularity, and just
It is to become an important hidden danger of optical cable safe and stable operation because of special position and stringent mounting process requirement,
Also it is a weak link of entire lightguide cable link.
It is a most common failure point at guiding cable sleeve in substation at framework, this is primarily due to there is no one at present
A unification, effective, standard waterproof block mode.To prevent extraneous rainwater, moisture, the erosion of salt fog, floating dust from causing substation
Optical cable and guiding Cable's Fault, can not normally transmit so as to cause energy communication service at framework, so must take into consideration rational
Method for blocking and measure.
The closure of guiding optical cable is mainly blocked using fire-proof mud at present, and only with fire-proof mud block can cause to block not
Firm, the problems such as not fastening, fire-proof mud is also easily influenced by external condition and gap or cracking occurs over time, is existed
Some potential safety problems.In addition directly casing nozzle is blocked using fire-proof mud, the fire-proof mud bottom at nozzle without support,
It is easy to cause and collapses or fall off, in winter under special weather, rainwater is easy to freeze in pipe, and leads to interruption of optical cables.By above
It can be seen that although which can protect optical cable under the drawing at framework in short term, over time, fire-proof mud can take off
It falls or cracks.Especially in winter, rainwater can be immersed in casing and be frozen, and eventually caused the Cable's Fault in casing, caused
Optical cable attenuation is excessive or interrupts.
In order to solve the problems, such as that optical cable plugging device uses for a long time, ensure long-term rain, snow, frost or hot environment
Under, it is applicable to be badly in need of a kind of reliable, service life length, appearance looks elegant, construction is simple, new site, transformation website of blocking of exploitation
Plugging device.
