The average person is easy to confuse the concept of flame-retardant cable and fire-resistant cable, although flame-retardant cable has many advantages more suitable for chemical enterprises, such as low halogen, low smoke flame retardant, etc., but in general, fire-resistant cable can replace flame-retardant cable, and flame-retardant cable can not replace fire-resistant cable.

Greased conductors in electrical cables offer several advantages that enhance the performance, durability, and reliability of conductors. The advantages are as follows:

The safety performance of wire and cable includes the safety performance of conductor materials, the safety performance of insulating materials, the safety performance of outer protective layer, and the use of wire and cable environment and power and other factors. The following will describe in detail the method of judging the safety performance of wire and cable.

In the field of electrical engineering, the choice of cable materials is crucial for ensuring safety and performance. Two popular types of cables are halogen-free cables and fire-resistant cables, each designed to meet specific safety standards and applications. Understanding the differences between these two cable types is essential for industry professionals and consumers alike.

The basic structure of the power cable consists of a core (conductor), an insulating layer, a shielding layer and a protective layer.

1. Electrical performance testing

Conductor Resistance: Tests the electrical conductivity of wire and cable, i.e. the resistance value, which is an important indicator to assess the ability of wire and cable to transmit current.

Insulation resistance: testing the resistance value of insulating materials to assess their insulation performance under the action of electric field to prevent current leakage and short circuit.

Industrial Frequency Withstand Voltage Test: Using AC voltage to conduct voltage withstand test on wires and cables to check whether their insulation performance is stable under the specified voltage.

Leakage Current (Leakage Current): Under the rated working voltage, the leakage current of the wire and cable is checked to ensure that it will not cause safety problems due to excessive leakage current under normal working conditions.

Tinde Cable, is a renowned cable manufacturer based in Zhengzhou, China, specializing in the development and production of high-quality cables and conductors for various applications, is leading player in the global cable manufacturing industry.

High-voltage cables are an essential part of our modern electrical infrastructure, transporting large amounts of electricity over long distances. While many cables are buried underground for safety and aesthetic reasons, high voltage cables are generally not buried underground due to various technical and practical challenges.

Copper-clad steel (CCS) has been a popular material in the telecommunications industry for decades. CCS stranded wire is composed of a steel core with a layer of copper cladding.

At the end of July, Tinde power cable received an urgent notice, because of the construction requirements of the winning bid, have to prepare all the conductors & cables of the project contract by August 31, 2024.
