Classification of nylon THHN wires

What is nylon THHN wire? Are there any specifications and types of nylon THHN wires? Why is nylon wire called nylon THHN wire?

Nylon threading hoses are divided into standard nylon hoses and flame retardant nylon hoses.

Standard Nylon THHN Hose

The inside and outside of the standard nylon THHN hose are wavy, the color is generally black, and there are other colors, and some can be opened, which is more convenient and quick to thread.

Its characteristics: good flexibility, anti-twisting, good bending performance, can bear heavier loads; acid, lubricating oil, coolant, etc., glossy surface, friction resistance; can withstand the heavy pressure of the foot, no fracture, no shape , can recover quickly, and does not have any damage itself.

Flame Retardant Nylon THHN Hose

The flame retardant nylon hose is wavy inside and outside, and the color is black.

Its characteristics: In addition to the characteristics of standard nylon THHN hoses, the flame retardant nylon THHN hose has better lubrication effect, higher friction resistance, faster rebound recovery, and can adapt to higher temperature working environments.
