What Types of H07V-U WiresAre There? What Are its Advantages?

H07V-U wire, commonly known as plastic hard wire, its full name is copper core polyethylene insulated cloth wire. "B" means the type is cloth wire and "V" means the insulation is polyethylene. Suitable for wires used in power systems with AC currents of 450/750V and below, Japanese high-power electrical appliances, instrument panels and communication products.Best building wire such as1.5 MM Single Core Copper PVC Insulated Electrical Cable Wire

1. Classification of H07V-U wires

H07V-U wires are classified according to their characteristics: they have two functions: flame retardancy and fire safety. The English letter data are ZC-H07V-U and N-H07V-U respectively. The application fields are as follows:
ZC-H07V-U: Copper core high-voltage polyethylene insulation layer insulated wire: Environmentally friendly flame retardant is added to the insulation layer material, which will not easily catch fire when left. The flame retardant H07V-U series products are divided into three levels: A, B, and C. Among them, the flame retardant level A is good, and so on, ZC-H07V-U is commonly used.
N-H07V-U: Copper core high-voltage polyethylene cable sheathed mineral insulated cable: can be used normally under any normal fire accident conditions.

2. Advantages of H07V-U wire

H07V-U is a common single-core hard cable used for interior decoration and lighting. In addition to cost-effectiveness, it also has the following two advantages:

1. 4mm2H07V-U is solid
In home decoration, the biggest external force suffered by cables is tensile force and pressure. In terms of tensile strength, a single copper core wire is stronger - in all processes of drawing and extrusion, the copper core wire is very easy to break, resulting in a reduction in the cable's current carrying capacity - very thin copper with a diameter of 0.41mm heart line

2. The H07V-U wire has a large current carrying capacity
In distribution lines with short-circuit faults, low frequency, low voltage, and small current (not considering the skin effect), the cable carrying capacity of single copper core cables exceeds that of multi-copper core cables.
