The LONGJOY NEMA cable ladder is a cable support system, with the following characteristics and uses:

• Stable structure and high strength. NEMA cable ladders can withstand large loads and shocks, suitable for heavy machinery and equipment cable laying.
• Good corrosion resistance. NEMA cable ladders can be painted, electro galvanizing, hot dip galvanizing, and other ways of surface treatment to improve their resistance to chemical media and electrolyte corrosion.
• Good heat dissipation performance. The structure of the NEMA cable ladder is in the form of a ladder, and there is a large gap between the side plate and the cross support, which is convenient for the heat dissipation and ventilation of the cable, and is especially suitable for laying high and low voltage power cables.
