Product introduction

The plastic-sprayed upward-curved circular accessories are specially designed for cable trough systems. They have won the favor of the market with their unique upward-curved structure and high-quality plastic-spraying treatment. The use of high-quality steel as the base material ensures the strength and stability of the accessories. The surface is treated with high-quality plastic spraying (>60um), with rich and durable colors, which not only improves the overall aesthetics, but also enhances corrosion resistance. The trough structure makes it easy to install and disassemble, and facilitates cable wiring and maintenance. The fully enclosed cable conductor design provides shielding and protection for the control cable, avoiding electromagnetic interference and physical damage. The unique upward-curved design makes the cable more flexible and convenient during wiring, especially suitable for occasions where wiring needs to be bent upward. Whether it is a data center, industrial plant or other places that require efficient cable management, this plastic-sprayed upward curved circular accessory is your indispensable choice.

Spray Plastic Up Round Bend Accessories for Cable Trough Systems
The Spray Plastic Up Round Bend Accessories are specialized components designed to facilitate the vertical directional change of cable management pathways. These accessories provide a curved transition for cable troughs, enabling wiring systems to ascend along walls or structural supports without compromising the bend radius of the cables. Constructed from carbon steel and treated with a thermosetting powder coating (spray plastic), these bends offer a protective barrier against environmental factors while ensuring a smooth internal surface for cable pulling. The "up round" configuration specifically manages 90-degree vertical upward transitions within modular cable trough layouts.
Environmental Resistance
Electrostatic spray plastic coating provides dense, non-porous layer that resists moisture, chemical vapors, and oxidation, extending cable management system service life.
Cable Protection
Rounded arc design maintains minimum bend radius required for power and data cables, preventing insulation stress and signal attenuation.
Electrical Insulation
Plastic coating acts as additional dielectric barrier, reducing risk of capacitive coupling and enhancing overall electrical installation safety.
Standardized Integration
Dimensions and bolt-hole configurations engineered to align with international cable trough standards, ensuring seamless connection with straight sections.

Underground Facilities – Corrosion-resistant transitions in subway stations, tunnels, and parking structures with high humidity levels.
Storage Conditions
  • Environment: Store in dry, ventilated indoor warehouse. Avoid direct exposure to prolonged sunlight or rainfall to prevent UV degradation of plastic coating prior to installation.
  • Stacking: Use protective spacers or original packaging between components to prevent spray plastic surface from scratching or chipping during bulk storage.
Installation Precautions
  • Fastener Selection: Use stainless steel or galvanized bolts for connections to maintain corrosion resistance integrity at joinery points.
  • Grounding Continuity: Since spray plastic coating is an insulator, ensure bonding jumpers are installed across joint to maintain electrical continuity for grounding purposes.
  • Edge Inspection: Verify no mechanical damage occurred to coating during transport; use touch-up spray for exposed metal to prevent localized oxidation.
