What is the difference between a wired H07V-K and a H07V-R?

Similarities between wire H07V-K and H07V-R

1. Both wires are soft wires, both are composed of multiple strands of copper wire, and are both called polyvinyl chloride insulated soft wires;
2. The structure is very simple, consisting of a conductor and a polyvinyl chloride insulation layer;
3. In terms of color, both have a variety of colors - red, yellow, black, blue, green, yellow-green (two-color), etc.4mmH07V-K、25mmH07V-K、16mmH07V-K

 Differences between wire H07V-K and H07V-R

1. Executive standard: H07V-R wire product standard is IEC60227, H07V-K wire product standard is IEC60227, EN50525
 

2. Rated voltage: H07V-R wires belong to the type of wires, and the general rated voltage is 300/500V, while H07V-K wires are mostly used inside the machine as connecting power lines, and have higher voltage requirements, with 450V/750V or higher 600/1000V ;
 

3. Product use: H07V-R wires are mostly used as cloth wires, and are used in occasions where softness is required for fixed wiring. In many cases, they can be used instead of BV wires. After all, H07V-R wires are softer; H07V-K wires are mostly used for various electrical appliances or mechanical internal connections. , security equipment, instruments and meters are often used, so the H07V-K line is softer, so it is named "electronic line";
 

4. Working temperature: The working temperature of conventional H07V-R wire is 70°C, and that of H07V-K wire is 80°C. Of course, if there are special requirements, you can choose the type with high temperature resistance;
 

5. Wire appearance: From the appearance point of view, there is a difference between the two. The H07V-R wire is softer than the H07V-K wire; secondly, the copper wire of the H07V-R wire is thicker than the copper wire of the H07V-K wire, which is why the H07V-K wire is softer. s reason
Fire-resistant wire and cable means that in a wire and cable fire accident, the wire and cable product can maintain normal operation for a certain period of time while the external flame is still burning, maintain the integrity of the wire and cable line and maintain the normal operation of the line equipment.
