Extruded insulating materials are polymer insulating materials, and their physical and chemical properties are determined by their chemical structure, chemical natural force and size. electrical properties of extruded insulating materials shall be graded according to their response under operating field strength. Under low operating field strength, the electrical properties of polymer materials used as cable […]

1、 Scorch 1. Scorch phenomenon (1) The temperature is too high, or the temperature control instrument fails, causing the plastic to burn at an ultra-high temperature. (2) The glue outlet of the machine head has large smoke, strong pungent smell and crackling sound. (3) Granular scorched matter appears on the plastic surface. (4) There are […]

Fireproof wires and cables are the general name of wires and cables with fireproof performance. They are usually divided into flame-retardant wires and cables and fire-resistant wires and cables. For some designers just engaged in electrical design, it is essential to understand some cable characteristics in the industry. Let’s talk about the difference between flame-retardant […]

Basic structure The basic structure of power cable consists of core (conductor), insulating layer, shielding layer and protective layer. (1) Core The core is the conductive part of power cable, which is used to transmit electric energy and is the main part of power cable. (2) Insulating layer The insulation layer is to separate the […]

PV cables are often exposed to sunlight, and solar systems are often used in harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, sunny days can lead to a site temperature of up to 100 ° C. At present, various materials available include PVC, rubber, TPE and high-quality cross-linking materials. Unfortunately, rubber […]
