Cable tray is assembled by pultruded GRP/FRP profiles; suitable for electrical cable, control cables,
lightening cable and fittings. There are fiberglass pipe, fiberglass tank, fiberglass tube and vessel.
1.Long service life ( normal design life is 20 years)
2.Convenient installation, and low cost (1/4 SG of carbon steel, no
need of fire during construction; length per piece can be 8 m, or
3.Easy to cut, no need of maintenance
KQJ series cable tray is suitable for voltage below 10 kV
electrical cables, control cable, and lightening fitting cables of
below 10 kV and the lay out for indoor, outdoor, aerial, channel
for cable and tunnel.
KQJ serial cable trays have the features that: widely used, high
strength, reasonable structure, low cost, easy for construction,
flexible fittings, nice-looking appearance, which make expansion,
rebuilding, maintenance much easier.
The installation of KQJ series cable tray can be per the local
conditions can be laid according to the process requirements, such
as plumbing, floor, hoisting under the beam, indoor and outdoor
wall, tunnel, cable trench side wall mounted, but also on the open
When height of groove of cable tray is 50,100 mm, 6 connection
holes for each end; when height of groove of cable tray is 150,200
mm, 12 connection holes for each end.
Support Spacing: it shall be less than or equal load curve,
allowable load and support span.
Width: when we are electing the width of cable tray, we should
leave enough spare space for new cables in the future.
Separated lying: when there are less power cables and control
cables, they can be installed in the same cable tray, but there
should be a separation plate between the power cable and control
Fixing of cables: when the cable trays are horizontal laid, the
connection point shall be in the position of 1 / 4, horizontal
cable shall be fixed every 2 meters, the vertical cable trays shall
be fixed every 1.5 meters.
Arrangement of cables in the cable tray
Weak current control cables shall be at the top layer, general
control cables and low voltage power cable are downward
arrangement. This kind of arrangement is good for shielding; good
for cooling and site construction.
Spacing between cable trays
To ensure easy installation, cable tray and the spacing must
satisfy the following data:
a ,when we are setting cable trays in the same support beam or in
the same horizontal level, the net distance between adjacent cable
trays should not be less than 50mm.
b, for two parallel cable tray, its net distance should not be less
When the cable trays are overlapped laid, the vertical distance
shall meet the following data:
a, for power cable, it should be 300mm.
b, the control cable, it should be 250mm.
For the convenience of cable tray installation, the distance
between cable tray and the top of the ceiling, beams and other
obstacles at the bottom should meet the following data:
a, for power cable, it should be not less than 400mm.
b, for control cable, it should be not less than 250mm.
Vertical cable trays must be protected by cover on the area which
is within two meters above the ground.
The position which is liable to mechanical damage must be protected
When the cable trays are horizontally laid, the selection of stride
support shall be per the load curve; when the cable trays are
vertically laid, there should be a fixing frame every 1 or 2 meters
to make sure the stability of the cable trays.
When the cables in the cable tray are lead from horizontal
direction to vertical direction, there must be a guide plate to
protect the cable from damage.
When the material of cable tray is steel, there should be a
reliable grounding wire; cable trays must be connected with the
main grounding wire.
Our company can produce the whole set of production line of Potassium Sulfate.
This technology is one of most advanced production methods of
potassium sulfate. The core is updated new reaction furnace based
upon the basis of dry baking method to produce the potassium
sulfate. Under the support of the special equipment, it has
resolved the abrasion and the corrosion under the condition of high
temperature and strong acid and the process problem of continuous
output. Comparing with the same equipment from foreign countries,
its outstanding characters are little investment, short building
duration (four to six months), high atomization reliable quality,
high heating efficient, high output, and environment protective.
The design, fabrication, installation, production process,
inspection and testing of this whole set of technique and
equipment, are completed by our Company singly. We have
successfully transferred the whole set of equipment and technique
to many firms in Philippines, Indonesia, India, Egypt, etc in
recent year, and got good effect.
Welcome clients, friends to our company to visit, consult, and
The technical parameters of the Potassium Sulfate produced by our
company are as following:
1. Can reach the following Spec. when Sulfuric acid and potassium
chloride are superior quality and have enough time to react:
Moisture content : 0.5%max
PH value: 6.5-7
2. Can reach the following Spec. on a large scale in practical
Moisture content : 1.5%max
