Advantages of copper core cable compared to aluminum core cable
1. High strength: Allowable stress at room temperature, copper cable is 7~28% higher than aluminum cable. Especially the stress at high temperatures, the difference between the two is even more distant. 2. Low resistivity: The electrical resistivity of the aluminum core cable is about 1.68 times higher than that of the copper core cable. 3. Good ductility: […]
What are the classifications of wire and cable?
There are many types, and the types are more complicated. Wire and cable are often used for the transmission of conductive transmission equipment. The following wire and cable manufacturers will introduce you to the classification and types of wires and cables. The first, bare wire refers to the product with only the conductor and no insulation layer. This includes […]
The structure and structure of wire and cable are small
Most of the wire and cable products are products with the same cross-section (cross-section) shape (ignoring manufacturing-related errors) and long strips, which are used as features in the system or equipment to form lines or coils. Determined. Therefore, research and analysis of the structural composition of cable products, only need to observe and analyze from its cross […]
Classification of causes of power cable failure
The nature and classification of cable faults1. Classification by fault material characteristicsIt can be divided into three types: series fault, parallel fault and composite fault.(1) series failureA series failure (metal material defect) is a failure in which one or more conductors of the cable (including lead and aluminum sheaths) are disconnected. It is a generalized […]
How to choose the common household wire models and specifications?
The specification of the wire is the line side — the cross-sectional area of the wire, in square millimeters, referred to as square or square — this sentence has been reduced to two words «line».The arrangement of the lines is leaping and there is no rule to follow. For example, there are 1 square wire, […]
