With the increasing use of heating cables for heating and warmth supply, a basic understanding of their structure is becoming increasingly essential. Anlete Heating Cables explains that the basic structure of most cables consists of four main parts: the conductor, insulation layer, shielding layer, and protective layer. The conductor is the core of the cable, used to transmit electrical energy and provide heating. The insulation layer electrically isolates the conductor from the ground and from conductors of different phases to ensure the transmission of electrical energy; it is an indispensable part of the cable structure, highlighting its crucial importance. So, what properties should the materials used for the insulation layer possess?
(1) High breakdown strength;
(2) Low dielectric loss;
(3) Quite high insulation resistance;
(4) Excellent discharge resistance;
(5) It possesses a certain degree of softness and mechanical strength;
(6) The insulation performance is stable over a long period of time.
The materials used for cable insulation include:
(1) Inorganic insulating materials: Commonly used inorganic insulating materials in power cables include mica, asbestos, marble, ceramics, and glass;
(2) Organic insulating materials: such as resin, rubber, paper, hemp, cotton yarn, etc. are commonly used materials for the insulation layer of power cables;
(3) Hybrid insulating materials: Hybrid insulating materials are a type of insulating material formed by processing the above inorganic and organic insulating materials.
Therefore, choosing a qualified heating cable is crucial, as high-quality cables will not cut corners in critical areas like the insulation layer. Chengdu Anlait has many years of experience in the R&D, production, sales, and service of heating cables. Anlait's high-temperature resistant double-shielded single/double-conductor heating cables use flame-retardant all-silicone rubber insulation, with a maximum temperature resistance of up to 260 degrees Celsius. Silicone rubber has excellent anti-aging properties, thermal conductivity, weather resistance, corrosion resistance, and high resistivity.
Therefore, those interested in electric heating should choose a reliable brand when selecting products.
