cable is connected to thousands of households,
are connected by cables and joints,
it can be said: "joint" deal with good or bad,
is one of the most important factors that affect the normal operation of the network,
cable tv network engineering,
is the "joint" project, which is our consensus.
rural cable network,
due to the limited level of technical personnel, tools are not available,
most of the use of manual, often not in strict accordance with the construction standards.
therefore, when the network is running for a period of time, the failure occurs frequently.
in the past, most of the maintenance records were caused by cable joints,
either the core line, bad contact, such a good fault exclusion.
another kind of fault is the cable joint water, serious short circuit, it is difficult to troubleshoot.
for example: the user reflects the normal day of the tv, the snow is very serious at night.
we use a variety of methods to find and narrow the scope of failure in a cable joint,
open the waterproof mortar and find the water in it. every night,
the air humidity is big, make the cable short circuit, the voltage drop,
to make the rear tv snow serious. in order not to water the cable,
we prepared several solutions, and finally selected the method of using soft plastic casing.
after two years of observation, basically solved the problem of cable water,
it is proved that this method is feasible,
a good way to work well.
this method is very simple,
is a soft plastic tube containing a 30-40 cm long,
its aperture in accordance with the cable used, a little larger also does not matter.
plastic pipe by joint with good zhasizha
(tie line with a twisted pair of telephone wires or -7 cable with copper core, in short, to fasten the principle)
in the lower part of a hole, size,
because the water flows from top to bottom, the cable is in water, it can not hide.
