Wiring Harness Details
- Pre-Wired Configuration: Facilitates quick installation and centralized distribution of power and data .
- Cable Type: PUR cables with high flexibility for constant motion applications .
- Phase Busbars and Droppers: For larger KVA distribution boxes, busbars are typically aluminum with cross-sections like 72×50×8 mm for 63/100 KVA and 112×50×15 mm for 160/315 KVA boxes; droppers match busbar cross-section .
- Insulation: PVC sleeves with standard color coding for different phases .
- Environmental Ratings: IP67 for unmated connectors; enclosures can withstand temperatures up to +70°C for short periods and humidity up to 90% at lower temperatures .
Key Considerations
- Customization: Labels, coding, and pre-wired options are available for specific industrial applications .
- Durability: Designed for harsh industrial environments, including resistance to oil, vibration, and chemical exposure .
- Compliance: Conforms to relevant standards such as GB7251.3-2006 for low-voltage switchgear and IS:13411 for isolators . This information provides a comprehensive overview of distribution box wiring harness specifications, including connector types, port configurations, cable lengths, materials, and physical dimensions, suitable for industrial automation, robotics, and power distribution applications.
