Wire slot made of metal or nonmetal materials, refractory, can assemble the wire or cable.
You can open the cover to facilitate online slot can be placed after the cable installation.
when a metal trough, outdoor applications, its structure should have waterproof function, not suitable for the following site:
1. Vulnerable to serious machinery impact and corrosive gas hazards.
2. Entities region of combustible gas and dust and high flammability areas.
2, non-metallic trough ( Such as PVC with the slot) Does not apply to the following places:
1. There is no shelter, vulnerable to external damage.
2. In addition to products of special instructions, the place of exposure in the sun.
3. There is the place of the corrosive gas.
4. Place in the damp environment.
5, products designated use temperature around the outside of the workplace.
3, in the same relative path does not have distribution equipment of electromagnetic compatibility test line can be placed in the same metal composite box. Slot electric conductors shall not exceed 30, a line of 20% of the total cross section shall not exceed the groove section.
it is charged with wire or cable lines and high-voltage lines cross section is beyond the 50% of the cross section of the groove, and the total cross-section of wires or cables. When the electromagnetic compatibility of routes and other routes shop
in the same metal material feed tube groove, the application of metal diaphragm barrier protection or blocking cable wires.
4, metal trough in the wire or cable should not be connected. When have a branch in the cable trough, the branch is head should be located in for installation and inspection place. Connection and interface of each transmission line, Contains the wiring and connectors)
the cross-sectional area shall not exceed the installation in the set point of wiring slot cross-sectional area of 75%.
5, the metal tank shall not be placed in the corrosive gas pipe and heat pipe, corrosive liquid and under corrosive liquid pipe. In case of difficulty, should take measures to prevent corrosion and heat insulation.
6, metal trough laid, appropriate to set support or brace in the following parts: 1, parallel lines do not exceed 1 m and to the end of the slot connection area; 2 from the trough the head end, end and junction box import and export of 0. 3, 5 m. Trough the corner part. When wire
groove parallel to the length of more than 30 m, should be set expansion joints. Across the building deformation connecting head to install compensation equipment.
7, aiming at building surface or the stiffness of supporting frame built plastic hose ( Slot) Should every 30 meters installed in the segments deformation cracks or other temperature pipeline compensator.
eight, if must, slot can be through the wall. The terminals of the slot should be closed.
9, metal cable trough and brace length should not be less than 2 with PE or PEN main wiring. PVC trough should be according to the different wiring method configuration separate equipment grounding line.
10, after installation trough, local label factory, should be in clear PVC with the line groove marks on the position of the obvious internal cross-sectional area.
trough installation:
1, the metal tank should be straight, not deformation, each component of uniform thickness, both ends of the cutting face shall be flat. Trough requirements, both inside and outside surface is smooth, inside of the damage wire not a protrusion.
2, after the installation work, should clean up all the surface. If the paint falls off or scratches in the whole construction process, response surface clean-up and anti-rust treatment before you wipe the same paint.
3, hot dipped galvanized cableway in the middle of the connecting plate is not grounding device in both sides, but on the opposite side of the connection plate has a loose nut or a seal ring, no less than two fixed anchor bolt.
4, vertical shaft in the trough and transcend different evacuation exit of the trough, should be set as stipulated in the design of fire and flood protection measures.
5, the position of the slot surrounding should be more than enough to wiring and maintenance.
6, all fixed screw should be used to protect the spring washer and nut.
7, please give trough the wire with appropriate sheath, or using other methods to avoid damage the insulation of the conductor.
8, for metal trough and accessories height less than the road 2. 10 meters, proposing a moderate collision avoidance countermeasures.
