High voltage cables carry enormous power. Any mistake in their support system can cause serious accidents. Arc flashes, electrical leaks, and interference between cables are real dangers. Standard cable trays do not address these risks. Our High Voltage Cable Tray is designed specifically for 10kV and 35kV systems. It keeps high voltage cables separated and secure. It prevents arcs and leaks. This tray is built for safety first.
Insulated Barriers and Strong Construction
The tray has a reinforced structure. The side rails are taller and wider than standard trays. This creates more space inside. Inside the tray, we install insulating divider plates. These plates separate each cable layer. They prevent contact between different voltage levels. The divider slots hold the plates firmly in place. For ladder-style trays, we space the rungs at 300mm. This tight spacing adds rigidity. It also reduces movement and vibration. The tray will not sway or shake. This is important because movement can cause arcs. We also smooth all edges. No sharp points. Sharp points concentrate electrical fields and can cause corona discharge.
Trusted by Major Power Projects
We have supplied High Voltage Cable Trays to State Grid projects. This includes installations in Xiong'an and Jiaozuo. These projects require the highest safety standards. Our tray meets JB/T 10216-2025 and CECS31 standards. The coating choices support safety. For indoor substations, we recommend electrostatic powder coating. This is a special insulating coating. It is 60μm thick. It resists arcing and prevents current leakage. For outdoor applications, we recommend hot-dip galvanizing. We also offer stainless steel. It has no oxidation points that could cause corona. Every accessory matches the high voltage standard. Splice plates, brackets, and bolts are all made to prevent leaks and arcs.
