Differences Between H05V-R, H07V-R Wires And H05V-K, H07V-K Wires

H05V-R and H07V-K building wire belong to flexible wires, but they are wires of different specifications, and the wires of small specifications are difficult to distinguish with human eyes. If you want to know the relationship between H05V-R wires and H05V-K, we In what ways do you differentiate?

1. H05V-R name: copper core polyethylene insulated soft wire; a cable product for transmitting electric (magnetic) energy, information and realizing electric energy conversion. It is composed of an insulating layer and an electrical conductor. It is a copper core PVC insulated flexible wire, which is used in places where the wires are fixed and flexible.

2. H05V-K name: Copper core polyvinyl chloride insulation layer connection soft wire; it is widely used in industrial production and distribution equipment, especially in flexible installation sites with strict requirements, such as electrical cabinets, power distribution Cabinets and various low-voltage electrical equipment can be used for transmission of electric power, electrical control signals and switch signals. 1.25mmH05V-K cables、2.5mmH05V-K and wires Single Core copper building wire PVC Insulation adopt a soft structure design, and the bending radius of the electric conductor is small, and it is suitable for installation sites that are wet, cold and oily.

Introduce the similarities and differences between the 2.5mmH05V-R wire and the H05V-K2.5mm wire in detail

1. Similarities:

① Both types of 300/500V H05V-K cables and 300v/500v H05V-R are soft wires, both of which are composed of multi-core copper wires, and are called PVC insulated flexible wires;

②The structure is very simple, all of which are composed of electrical conductors and PVC cable sheaths;

③In terms of color, both have a variety of colors-red, yellow, black, blue, green, and yellow-green.

2. Differences:

①Specification: The implementation standard of H05V-R wire products is IEC60227, and the implementation standard of H05V-K wire products is IEC60227 EN50525;

②Working voltage: H05V-R wires belong to the category of cloth cables, and the general rated current is 450/750V, while RV wires are mostly used in mechanical equipment as connecting switch power cords, and the working voltage requirements are higher, with 450V/750V Or higher 600/1000V conductors: H05V-R conductors belong to Class 2 soft conductors; H05V-K conductors belong to Class 5 conductors;

③Main use: H05V-R wires are mostly used as wiring cables to fix places that require softness when routing. In many cases, they can be used instead of H05V-U wires. After all, H05V-R wires are softer; H05V-K wires It is mostly used for internal connection wires of various household appliances or mechanical equipment, and it is often used in security products and instrumentation equipment, so the H05V-K wire is softer, and it is also known as "electronic wire".

④Temperature: The operating temperature of the basic H05V-R wire cannot exceed 70°C, and the operating temperature of the H05V-K wire can reach 80°C. Of course, if you have special requirements, you can buy a heat-resistant type.

⑤ Surface: From the surface, there are differences between the two. The H05V-K wire is softer than the H05V-R wire, and secondly, the copper wire of the H05V-R wire is thicker than the H05V-K wire, which is why the H05V-K wire is softer.
