All factory electrical bracket layout electrical bracket layout designs strictly follows international and domestic industrial electrical construction standards (GB 50168-2018, GB 50217-2018), adhering to the five core principles of or standard industrial electrical installation: stable load-bearing, layered classification, safe distance, convenient maintenance, and environmental adaptation: to ensure compliant and reliable cable support systems.
2.1 Layered Layout & Voltage Classification Principle
For multi-layer bracket and multi-tray laying, lay cables in industrial factories, all cables must be laid in strict accordance with the voltage level from strong to weak (bottom to top): high-voltage power cables → low-voltage power cables → instrument control cables → weak current communication cables. This professional layered electrical bracket layout layout effectively avoids electromagnetic interference between strong and weak current circuits and ensures stable signal transmission and power supply quality for factory electrical equipment.
Standard layer spacing: ≥300mm between power cable layers, ≥200mm between control cable layers, and the net distance between layers shall not be less than 2 times the cable outer diameter plus 10mm; 35kV and above high-voltage cables need a minimum spacing of 2 times the outer diameter plus 50mm.
2.2 Safe Spacing Layout Standard
Strictly control the distance between electrical brackets and factory process pipelines, heat sources, and building structures to avoid safety risks:Standard electrical bracket spacing layout strictly controls the distance between factory electrical brackets, industrial process pipelines, heat sources, and building structures to eliminate potential electrical safety hazards in factory operation:
- Parallel laying with ordinary process pipelines: spacing ≥0.5m
- Parallel laying with thermal pipelines: spacing ≥1.0m (avoid heat-induced cable capacity attenuation, 10℃ temperature rise will cause 2%-3% cable capacity drop)
- Cross laying of all pipelines: spacing ≥0.3m
- Brackets installed through fire walls and floor slabs: brackets must be set on both sides of the fire wall with a spacing ≤1.0m, matched with fire blocking treatment
2.3 Load-Bearing & Deflection Control Principle
The bracket layout spacing is scientifically set according to the cable total load and tray material to ensure structural stability and no permanent deformation:The installation spacing of industrial electrical support brackets is scientifically configured according to the total cable load and tray material to guarantee structural stability and zero permanent deformation of the factory cable support system:
- Steel cable tray brackets: standard spacing 1.5m-2.0m, maximum deflection ≤1/200 of the span
- Aluminum alloy tray brackets: standard spacing 1.2m-1.8m, maximum deflection ≤1/150 of the span
- Heavy-load cable and large-span laying: reduce spacing appropriately and add auxiliary reinforcing brackets
2.4 Neat & Maintainable Layout
All brackets Standardized factory electrical bracket installation requires all brackets to be installed horizontally and vertically with uniform spacing. Avoid Random crossing and overlapping of cables. Reserve factory cables are strictly prohibited. Sufficient operation and maintenance space on both sides and upper and lower parts of reserved around the bracket system to facilitate later cable detection, replacement, and electrical equipment maintenance. The turn bending position of the electrical bracket matches the cable bending radius (≥10 times the cable outer diameter for ordinary cables, ≥15 times for high-voltage cables) to prevent cable insulation layer damage.
