METAL ELEMENT OF CABLE TRAY SYSTEM OR CABLE LADDER SYSTEM Russian patent published in 2021 - IPC H02G3/04 F16L3/00 

FIELD: electricity.

SUBSTANCE: invention relates to products used in a cable tray system or in a cable ladder system, i.e. in cable support systems, and is designed for laying cables and/or installing other electrical equipment of electrical installations and/or communication networks on them. To obtain elements of the cable support system with high dielectric properties, resistance to aggressive media, anti-corrosion properties, resistance to mechanical stress, a polymer protective coating with a thickness of 100-500 microns is applied to the steel element of the cable support system, obtained from a two-component polymer composition with a dispersion of 160 to 350 microns based on low and high density polyethylene, with melt flow rates of the first component from 10.0 to 20.0 g/10 min, and the second component from 0.1 to 9.99 g/10 min, with functional additives including an elastomer, an antioxidant stabilizer, a nanosized filler based on a clay mineral of the smectite type and a complex of halogen-containing and halogen-free flame retardants.

EFFECT: invention provides high dielectric, mechanical and operational properties of the cable support system for operation in highly humid and polluted environments.
