The installation tips of PVC row trunking mainly include the following aspects, which will ensure that the cable trunking is installed firmly and beautifully:
Select cable trunking specifications:
Choose the appropriate PVC row trunking specifications according to the diameter and number of wires and cables to be routed. Common specifications include widths such as 25mm, 30mm, etc., and height and length are customized according to actual needs.
Positioning and marking:
Before installation, clearly mark the location of electrical equipment such as lighting, sockets, and distribution boards, and plan the circuit direction on the drawing to determine the installation route of the cable trunking.
Use a pencil or marker to draw the installation location of the cable trunking on the wall to ensure the accuracy of the location.
Slot plate fixing:
For PVC cable trunking of different specifications, the fixing method is different. For example, for cable trunking of 2520-2530 mm, each fixing point requires more than 2 screws, and they must be arranged horizontally. For cable trunking above 25*30 mm, each fixing point requires more than 3 screws, and they must be arranged in a trapezoidal shape to ensure uniform force.
The trough plate cannot pass through or be buried in the wall, nor is it allowed to pass directly through the floor. The trough plate can be placed on the embedded parts, such as protective tubes or wooden dowels.
The splicing method of the trough plate needs to be arranged according to the line. Common methods include butt joint, corner splicing, cross splicing, etc.
Laying the wire:
After installing the trough plate, place the wire into the wire trough. Note that two wires of different wires or different circuits cannot be placed in the same wire trough. Only one wire can be placed in each trough.
The wires placed inside the trough plate must not have joints. If there are joints, a junction box should be installed at the joint for easy maintenance.
Wire connection:
When connecting the wire, be careful not to damage the core wire when cutting the insulation layer of the wire. The winding method should be correct, and it needs to be straightened after winding.
Fixing the cover plate:
Finally, cover the wire with the cover plate, and make sure that the nails are hammered in vertically to avoid damaging the wire.
Precautions:
Be careful not to damage the surface structure of the object during installation to ensure that the wiring is more beautiful.
After installation, remember to check the relevant lines and the insulation performance to ensure safety.
Following the above tips, you can ensure that the installation of PVC row trunking is both firm and beautiful, while ensuring the safe operation of the circuit.
