IEC 60840 Cable
IEC 60840 specifies test methods and requirements for power cable systems, individual cables and accessories, fixed installations, and rated voltages above 30 kV (Um=36 kV) not exceeding 150 kV (Um=170 kV). These requirements apply to single-core cables and individually shielded three-core cables and their accessories for the usual installation and operating conditions. However, they do not apply to special cables, such as submarine cables and their accessories, as it may be necessary to modify standard tests or set special test conditions.

How to Choose High Voltage Cables
The components of a high-voltage cable from the inside out include conductor, insulation, inner sheath, filler (armored), and outer insulation. Of course, armored high-voltage cables are mainly used for underground burial, which can resist high-strength compression on the ground and prevent other external damage at the same time.
1. voltage cable wire surface markings according to the standard, the wire surface should have the manufacturer’s name, product model, and rated voltage continuous markings.
This is conducive to the use of the wire in the process of problems that can be found promptly when the manufacturer and consumers must pay attention to this point when buying wire.
At the same time, consumers should pay attention to the manufacturer’s name, product model, rated voltage and wire surface of the printed logo is consistent with the purchase of wire to prevent counterfeit products.
2. Voltage cable wire appearance in the purchase of wire should pay attention to the appearance of the wire should be smooth and flat, with insulation and a sheath layer without damage, logo printing is clear, no greasy feeling when you touch the wire.
From the cross-section of the wire, the thickness of the insulation or sheath on the entire circumference of the wire should be uniform and should not be partial core, the thickness of the insulation or sheath should be.
3. High-voltage cable use specifications should be standardized by wiring fixed lines using BV single-core wire through the pipe.
Be careful not to touch the wires when wiring, and not to touch the wires when decorating the room. Do not join in the middle of a line. Do not touch the line when the wire is connected to the electrical box (box).
4. High-voltage cable conductor diameter in the purchase of wire should pay attention to whether the conductor diameter and the cross-section are expressed on the certificate of conformity. If the conductor cross-section is small, it is easy to make the wire heat caused by a short circuit.
It is recommended that the family lighting line with wire 1.5 square millimeters and above specifications.
Air conditioners, microwave ovens, and other household appliances with greater power should use 2.5 square millimeters and above the specifications of the wire.
