Everything about Double-Strap Flat Insulator
You might find it interesting to know about the insulators used in the surface-mounted wirings at your home or workplace. The double-strap insulator is utilized in nylon wires used extensively in construction wiring. The properties of the double-strap flat insulator are analyzed here.
What is Double-Strap Flat Insulator?
The double-strap flat insulator is a polymer product made from PVC in accordance with IEC 60227. This insulator is sufficiently resistant to the electrical current heat. Highly durable, it can be used for years without any failure or need for replacement. The double-strap flat insulator can be known as nylon wires or double surface-mounted wire on the market.
The double-strap flat insulator is usually white; however, it can be manufactured in other colors (e.g., black and red) based on customer orders. Since this insulator can also be used in single layers, double-strap surface-mounted wires are famous for being white on the market.

Applications of Double-Strap Flat Insulator
Double-strap flat insulators are commonly used for construction purposes due to their concurrent stability and elasticity. Nylon wires are utilized to connect the power to electrical devices, implement surface-mounted wiring, and wire the lighting systems of buildings. These wires are usually used in interior environments such the interior spaces of homes and buildings, for they have limited resistance against mechanical pressures. Furthermore, it is prohibited to install them in high-temperature environments.
Final Words
The double-strap flat insulator is known as the PVC/D insulator. The two strings used in nylon wires are placed in parallel. These flexible wires can only be used in places where there is limited mechanical pressure.
