The main role of heat shrink tubing in a circuit is to protect important devices and circuits from damage and impact. Although it does not have any particular impact on the operation of the circuit, it is often the key point that determines the success or failure of the entire design. With the rapid development of the electronics industry, flame-retardant heat shrink tubing is also inseparable from the electronics industry, more and more electronic products need to use flame retardant heat shrink tubing for protection. The flame retardant processing of the heat shrink tube, when attacked by external fire sources, can effectively block, delay or stop the transmission of flame, to achieve the effect of flame retardant.

铝芯复合芯电缆 (ACCC) 优势介绍
现在, 架空电缆用于长距离输电. 常规电缆多为铝导体钢增强 (钢芯铝绞线). 自 1990 年代以来, 碳纤维复合芯材 (aluminum conductor composite core) have been used as the core bar of cables. ACCC has the following advantages over traditional conductors.
电线电缆导体预热时需要注意什么?
Wire and cable are used to transmit electrical (磁的) 活力. 线材产品的信息与电磁能量转换的实现. 广义上讲, wire and cable are also referred to as cable, and narrowly speaking, cable refers to insulated cable. It can be defined as a collection of the following parts: one or more insulated wire cores, and they may have their cladding, total protective layer, and outer sheath, the cable can also have additional conductors without insulation.
电线杆上的白色陶瓷——电绝缘体
The main role of electrical insulators is to provide mechanical fixation and electrical insulation for electrical equipment and conductors in power transmission and supply lines. Insulators are currently available in three main materials, namely ceramic, tempered glass, and organic composite materials. Insulators have played an important role in the development of the electric power industry.
如何使用接线端子
接线端子用于方便接线. 它是用绝缘塑料密封的金属片. 两端有孔可插入电线, and screws are used for fastening or loosening. 例如, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and disconnected at any time, It is convenient and fast without welding or winding them together.
影响电线电缆产品绝缘电阻的因素
The insulation resistance of wire and cable products mainly measures the volume resistance of the cable insulation layer, 无法测量表面电阻, and more factors affect the value of cable insulation resistance. In practical application, there are four main factors on the insulation resistance coefficient.
提高铝合金芯铝绞线综合性能的小窍门
The rated breaking force of the conductor is calculated based on the strength of all the aluminum single wires and reinforcements. 然而, the actual braking force deviates from the true calculated value. The main reason for this is that the strength of every single wire is not fully utilized. 所以, when designing the product not only to meet its minimum strength requirements but also to consider how the strength of every single wire is tapped out. Not only is it a full use of the material, but the overall performance of the wire will also be greatly improved.

Conductor Performance
Although high conductivity is an important indicator of a good or bad conductor, 还必须考虑其他因素. 银似乎是良导体. 然而, its high cost makes users have to turn to other alternatives. Silver also has other disadvantages, such as lack of physical strength, which is necessary for the process of cable laying into the pipeline.
