Wires and cables are generally coiled on
the cable spool for transportation, storage and laying release. Long length
cables under 30m can also be stacked into a social circle according to the
minimum bending radius not less than the allowable cable, and bundled in four
places at least for transportation. Cables, mining cables used to be mostly
made of wood in the cable reels, but now more common in steel frame structures.
Because the steel frame structure is relatively firm and not easy to be
damaged, it is very beneficial to maintain the cables, and this type of cable
reel can It can be reused many times and is more economical than wooden cable
reels. In the whole process of transporting and loading and unloading the cable
reel, the important problem is not to damage the cable, and not to damage the
insulation layer of the cable. Although it is a well-known problem, it still
occurs frequently and should be given sufficient attention.
1. Cable spool transportation
A crane is generally used to install the
cable spool. When the cable spool is transported in the car, the foot massage
sofa should be placed upright and firmly fixed, and the edge of the cable reel
should be padded to prevent the cable reel from shaking, colliding with each
other or falling. .
The cable should be inspected before
transportation. The cable should be intact and the cable end should be tightly
sealed; the inner and outer edges of the cable and the oil pipeline between the
oil-type cable and the working pressure tank should be firmly fixed on the
plate. Prevent it from being shaken and loosened during the whole process of
transportation; the oil gate valve provided on the working pressure box should
be open, and the working pressure indicates that everything is normal; the
outside of the cable should be well protected to prevent damage from foreign
objects. If a problem is found, it should be solved before it can be loaded and
shipped. The cable spool does not allow lay flat loading. Lying flat will
loosen the cable spool, and it is also very easy to damage the cables and cable
spools.
2. Cable spool unloading
It is prohibited to immediately push the
cable spool off the transport vehicle without lifting gear when unloading. Due
to the immediate push down, not only the cable spool is damaged, but also the
cable is easily damaged by mechanical equipment. Smaller and medium-sized cable
reels can be made of wood panels to form a steep slope, and then the cable reel
can be pulled down by a hoisting winch or rope and gradually rolled down the
steep slope. When loading and unloading the cable spool, it is forbidden to
lift two trays at the same time.
3. The flip of the cable spool
When the cable reel is turned over on the
road, it must be used within a small spacing range. The orientation of the flip
must be in accordance with the orientation shown on the side of the cable reel
(along the taut orientation of the cable). If it is turned in the opposite
direction, the cable will be unwound and loose and fall off.
The cable spool uses safety instructions,
and the application of mobile cable reels is similar to the power plugs that
everyone touches every day. They are all for the convenience of daily
production and manufacture of mobile chargers for daily life. Then the
electricity safety of moving the cable reel is similar to the electricity
consumption of everyone's daily life.
Whether it is a common problem in the
office environment or the safeguard measures in the application of power
strips, the two have similarities, so what are the basic common sense of
electricity safety that everyone should know? First of all, the mobile cable
reel should not be overloaded with electricity during use.
In order to better ensure that there is no
overload operation in the power supply circuit, in order to better ensure the
safety of the moving cable reel, each product is equipped with an
over-temperature load and leakage protection switch, which will be fully
automatic after loading. Bump.
Secondly, high-power sockets are usually
equipped with three-pin power sockets, in order to better ensure a safe
grounding device during the whole process of plugging in; and in mobile cable
spools, all control panels are equipped with three-hole grounding sockets.
Third, in daily life, when moving the cable
spool, it is not possible to replace the fuse wire with thin copper wire, nor
replace the heating wire with wire-covered wire.
Fourth, turn off the power when people walk
away, and the main power switch must also be turned off when the power is cut
off to prevent safety accidents when making calls. When used in industrial
production sites, if the power is turned off, the electric welder should be
contacted to check that there is no problem or repair before it can be used
again.
Fifth, it is not necessary to place the
mobile cable spool in a humid and cold environment with flammable materials.
Although the industrial production cable reels have a moisture-proof effect,
the long-term exposure to the humid and cold environment will also endanger
their normal work. Secondly, there are flammable items in the office
environment, which will cause a fire when the current is loaded or the ignition
of the switching power supply occurs.
