Determine the continuous operating current of the cable by considering factors such as the installation method and ambient temperature, then select an

This is the most traditional and widely used method. It employs a power-frequency AC test transformer to apply an AC voltage—within a specified freque

In industry practice, low-voltage cables generally refer to power cables with a rated voltage of 1,000 volts or less. Specific standards and specifica

A withstand voltage test—as the name implies—is a procedure designed to determine whether a cable’s insulation structure can endure a specific voltage

AC Withstand Voltage Test: For low-voltage cables with a rated voltage not exceeding 3 kV, a 50 Hz AC voltage is applied, with a peak value equal to 2

During production and operation, low-voltage cables may be subjected to various forms of stress, such as mechanical pressure, voltage surges, electric

The traditional production process for heat-resistant aluminum alloy conductors primarily involves steps such as aluminum melting, in-furnace refining

Bare conductors refer to wires that are not covered by any insulating material; they are typically used in high-voltage power transmission lines. The
