How to Calculate Voltage Drop
Voltage drop describes how the supplied energy of a voltage source is reduced as electric current moves through the passive elements (elements that do not supply voltage) of an electrical circuit. Voltage drops across internal resistances of the source, across conductors, across contacts, and across connectors are undesired; supplied energy is lost (dissipated).
The voltage drop of any insulated cable is dependent upon the cable length (in meters), the required current rating (in amperes), and the relevant total impedance per unit length ...

Welding Cable Introduction
What is welding cable?
Welding Cable, so-called welding lead, is intended for supplying power to an electrode in an electrical arc welding application. It is a specially designed metal rod, that conducts a charge. The charge carried by the electrode is required to make an electric arc, that heat sources, between the electrode and the metals or other welding materials, being welded. welding cable usually is the electrical cable to carrying welding current.
Welding cables are specially designed cable for use in secondary ...

Why you need the armored electrical cable
What is the armored electrical cable?
Armored electrical cable refers to a cable with a metal armored protective layer. The purpose of the armored layer is not only to increase the mechanical protection and elongation service life such as tensile strength and compressive strength but also to improve the cable's anti-interference performance through shielding protection.
Types of armored electrical cable
The armored electrical cable usually has some armored layer beneath the outer jacket to protect the integrity and electrical performance of the cable structure ...
