What is the PVC trunking
Cable trunking, also known as wiring ducts, distribution ducts, and row cable ducts, are used to organize power cables, data cables, and other wires in a standardized manner and are used to secure electrical equipment to walls or ceilings. Cable trunking is classified into various types based on their material, with commonly used types including environmentally friendly PVC cable trunking, PPO cable trunking, PC/ABS cable trunking, and metal cable trunking such as steel and aluminum. PVC cable trunking are an electrical wiring material made of polyvinyl chloride (PVC) and have insulating, self-extinguishing, flame-retardant, and arc-proof properties. They come in a variety of sizes, including 20mm×12mm and 40mm×20mm. After installation, wiring is neatly arranged and maintenance is facilitated. Common models of Canaletas de PVC include the PVC-20 series and the PVC-25 series, which are widely used for internal wiring in electrical equipment to protect circuits and mechanical equipment. According to different usage types, common wiring trunking include insulated wiring trunking, split wiring trunking, mini wiring trunking, partitioned wiring trunking, interior decoration wiring trunking, integrated insulated wiring trunking, telephone wiring trunking, Japanese telephone wiring trunking, open wire wiring trunking, round wiring trunking, exhibition partition wiring trunking, round floor wiring trunking, soft round floor wiring trunking, and covered wiring trunking.

How to choose a PVC trunking factory
- PVC Trunking Manufacturer Strength: For professional PVC trunking manufacturers, factory production strength is crucial. Manufacturing capabilities can better reflect their value. Automated production equipment and testing equipment are also important considerations.
- PVC Trunking Specifications: Trunking comes in a wide variety of sizes, and in actual use, you may need different sizes. If a PVC trunking manufacturer offers a wide range of specifications, you can purchase everything in one place, saving time and effort.
- PVC Trunking Certification: Regardless of the PVC trunking manufacturer you choose, certification is crucial as it can be used to assess quality. Common certifications such as UL94V0 flame retardant, CE, and ROHS are essential.
- Material and Craftsmanship: Verify that the raw materials are virgin PVC, avoiding recycled materials (this can be determined by smell; high-quality products have no pungent odor). Toughness Test: Test the trunking sample by bending it. High-quality products are resistant to breaking and quickly recover. Surface Treatment: Observe the surface of the trunking for a smooth, free of bubbles, cracks, and burrs.
- Price and Brand: Prioritize manufacturers with robust quality control systems. While ensuring quality, compare prices for similar products and choose suppliers with the best value for money.
PVC trunking installation
PVC trunking pre-Installation Preparations
1. Tools and Materials: Prepare an electric drill, screwdriver, hacksaw, measuring tape, PVC cable duct and accessories (elbows, connectors), self-tapping screws/expansion screws/glass glue, and other fixing materials.
2. Safety Verification: Disconnect power to the relevant area and mark the location of pre-buried pipes on the wall to prevent damage.
PVC trunking Core installation steps
1. Route Planning.
Run cables horizontally or vertically, avoiding intersections and frequent turns.
Keep cables at least 50 cm away from heat and water sources. Run cables separately for high-power equipment such as air conditioners.
2. Fixing Implementation.
For exposed wall mounting: Install fixing points every 1 meter. Use expansion screws for concrete walls and a pneumatic nail gun for brick walls.
For suspended ceiling mounting: Use hangers or bracket bridges, with load-bearing parts spaced ≤ 1 meter apart.
Screw Configuration: For cable trays under 25 x 30 mm: Use 2-3 horizontal screws per fixing point. For cable trays larger than 25 x 30 mm: Use 3-4 trapezoidal screws.
3. Connecting Cable Trays.
Reinforce straight sections with connectors and use specialized elbow fittings at bends.
Use metal hoses at the junction of the ceiling and wall.
Key Considerations
- 1. Load Control: No more than four conductors should be placed in a single cable tray, and the total cross-sectional area should be ≤ 40% of the cable tray’s cross-sectional area.
- 2. Safety: Cable trays for both power and weak current cables should be spaced ≥ 50cm apart, and the covers should be closed promptly after wiring.
- 3. Workmanship Standards: Cable tray joint tolerance ≤ 2mm. Levelness deviation ≤ 3mm per meter, ≤ 10mm over the entire length.
