Galvanised Cable Trunking: Heavy-Duty Steel Protection for Power Networks
In commercial high-rises, industrial manufacturing plants, and underground utility corridors, primary electrical distribution requires maximum physical containment. Cable pathways must resist severe mechanical impacts, contain power cable weight, and maintain continuous ground fault safety across long service runs.
Vich (CNVICH) manufactures heavy-duty Galvanised Cable Trunking engineered from high-tensile steel sheet metal. Featuring precision-formed locking lips and protective zinc coatings, our galvanized trunking systems deliver enclosed, crush-resistant routing for heavy power and control circuits.
1. Key Industry Pain Points Solved
-
For Electrical Contractors (High Impact & Load Defense): Protects heavy copper power feeders from accidental mechanical impacts, forklift collisions, and crushing forces in busy industrial zones.
-
For Building Managers (Fire & Debris Containment): Non-combustible steel construction acts as a continuous fire barrier, containing potential internal wire arcing while sealing cables away from airborne dust and combustion hazards.
-
For Procurement Teams (Cost-Effective Scalability): Delivers the most cost-effective per-meter enclosure cost for heavy-gauge power runs compared to aluminum or stainless alternatives.
2. Core Product Advantages: Why Choose Vich Galvanised Trunking?
-
Dual Zinc Coating Options:
-
Pre-Galvanized (PG / Sendzimir): Smooth, uniform zinc coating ($12–15\ \mu\text{m}$) ideal for commercial building risers, parking garages, and dry interior plenums.
-
Hot-Dip Galvanized (HDG): Heavy zinc layer ($60–80\ \mu\text{m}$) applied after fabrication to seal cut edges and welds for humid, outdoor, or sub-surface applications.
-
-
Precision Turn-Lock Covers: Features quick-turn fasteners or snap-lock lids that remain securely locked under vibration while granting quick access during maintenance audits.
-
Integrated Earth Continuity: Manufactured with pre-punched grounding points and bonding continuity links to ensure full NEC/IEC electrical grounding path compliance.
-
Multi-Compartment Dividers: Optional snap-in steel separation fillets allow high-voltage power lines and low-voltage control circuits to run inside the same trunking body without signal crosstalk.
3. Galvanised Steel Trunking vs. Plastic (PVC) Trunking
| Selection Criteria | PVC Plastic Trunking | Vich Galvanised Steel Trunking |
| Mechanical Impact Resistance | Low (Brittle under cold or high impact) | Maximum (Crush-resistant steel body) |
| Fire Safety Rating | Combustible / Releases toxic fumes | Non-Combustible (Zero toxic smoke) |
| Grounding & Shielding | Non-conductive (Zero EMI shielding) | Continuous Grounding & EMI Shielding |
| High-Amperage Load Capacity | Flexes under heavy cable weight | Rigid (Supports heavy power feeder bundles) |
4. Frequently Asked Questions (FAQ)
Q1: When should an engineer specify Hot-Dip Galvanized (HDG) over Pre-Galvanized trunking?
Answer: Pre-Galvanized trunking is ideal for dry indoor commercial spaces and ceiling voids. Hot-Dip Galvanized trunking should be specified for outdoor environments, humid plant interiors, or sub-surface tunnels where a thicker zinc barrier ($60–80\ \mu\text{m}$) is needed to resist atmospheric corrosion along cut steel edges.
Q2: How do multi-compartment dividers work in galvanised cable trunking?
Answer: Galvanised trunking can be fitted with removable internal steel dividers. These metal partitions physically segregate high-voltage power feeds from sensitive low-voltage data cables within a single trunking run, preventing electromagnetic interference while saving overhead ceiling space.
