How to Wire a Manufacturing Plant Network？

Factory Network Cabling

• Routing: Mainly use suspended cable trays for cabling. Terminal panels connect to the wiring district via metal pipes and cable trays.
• Inter-District Cabling: Use outdoor armored multi-core single-mode optical fibers to connect multiple wiring districts.
• Terminal Jumpers: Employ FTP shielded jumpers to prevent noise interference. For long-distance twisted-pair cables not installed in metal troughs or pipes, use shielded cabling.

Construction Specifications for Electrical Cabling in Factory Workshops

1. Conduit and Raceway Installation
   • Use PVC pipes for concealed wiring and PVC trunking for exposed wiring to protect hidden lines.
   • Lay single-strand copper wires with plastic or rubber insulation (diameter 1.5–2.5 mm). For parallel installation of live, neutral, and ground wires, wrap them in a plastic tube for dual insulation.
2. Distribution Box with Leakage Protection
   • Install a distribution box with a residual current circuit breaker (RCCB). The RCCB will trip automatically in case of leakage (e.g., live equipment casings or electric shocks) to ensure safety.
   • Choose renowned brand circuit breakers for the distribution box to guarantee power distribution safety.
3. Socket and Switch Installation
   • Follow the wiring rules: "Live wire into switch, neutral wire into lamp holder" and "Left neutral, right live, upper ground."
   • Color-code phase, neutral, and ground wires: neutral (black), ground (double-color). Use high-quality products for installation.
4. Wire Color Coding
   • Clearly distinguish live, neutral, and ground wires, and use standardized color coding for cables.

Key Considerations for Factory Workshop Cabling

1. Underground Pipeline Cabling
   • Use underground pipelines for complex structures to organize wiring.
2. Environmental Protection Measures
   • For workshops with electromagnetic radiation, dust, noise, vibration, or chemical reagents, adopt anti-EMI, rust-proof, dust-proof, oil-resistant, and waterproof measures. Ensure products and accessories meet or exceed national protection standards.
3. Main Cable Tray Design
   • Design main cable trays to cover the entire workshop, using metal trays for the main trunks.
4. Twisted-Pair Cabling Limits
   • Keep the total cabling distance between network terminal devices and interfaces within 90 meters for twisted-pair designs.
5. Electromagnetic Isolation and Surge Protection
   • Ground twisted-pair cabling and use pipeline protection for good electromagnetic isolation and surge protection. Separate data cables from other types of cables during routing.
