X mechanical and Electrical Equipment Co., Ltd. is a company engaged in mechanical and electrical equipment, gas explosion-suppression equipment key components of the design, production, processing, testing, sales of self-produced products and related products maintenance, after-sales service and technical support enterprises. Customers main products: coal mine explosion-proof equipment, customers use our products: red, yellow, blue heat shrinkage pipe.

Examples of specific application products: explosion-proof LED mine lamp, explosion-proof coal mine level sensor

Case study:

A, since it is used in coal mine explosion-proof equipment, so the quality of the heat shrinkable pipe that is, mechanical properties are the premise of protection, so double-walled heat shrinkable tube or medium and thick wall heat shrinkable tube become the first choice

B, safety problems: because the heat shrinkable pipe is mainly used in the mechanical joints of explosion-proof equipment, pressure resistance is the focus of consideration, the general pressure rating of 600V heat shrinkable tube is enough

C, life, environmental protection and other issues: taking into account the harsh environment of coal mine applications, the material of heat shrinkable pipe should be selected in the middle and high-end grade, because the quality of the material and the service life of the Heat shrinkable pipe is closely related.

D, color recognition problem: coal mine working environment is usually darker, heat shrinkable pipe can often play the role of color recognition, especially the connection of the grounding line, can be used to use yellow-green heat shrinkable tube or bright color heat shrinkable tube to distinguish, in order to play the role of safety labeling.

热缩管在煤矿防爆设备中的应用

X机电设备有限公司是一家从事机电设备,瓦斯抑爆设备关键部件的设计,生产,加工,检测,销售自产产品及相关产品的维修,售后服务及技术支持的企业。客户主营产品：煤矿用防爆设备，客户使用我司产品：红、黄、蓝热缩管。

具体应用产品举例：防爆LED矿灯，防爆煤矿液位传感器

案例分析：

a、既然是使用在煤矿防爆设备上，所以热缩管的质量即机械性能是保障的前提，所以双壁热缩管或者中厚壁热缩管成为首选

b、安全问题：因为热缩管主要应用在防爆设备的机械接头处，耐压是考虑的重点，一般耐压等级为600V的热缩管已经足够了

c、寿命、环保等问题：考虑到煤矿应用的恶劣环境，热缩管的材质应选在中高端档次，因为材质的好坏与热缩管的使用寿命息息相关。

d、颜色识别问题：煤矿工作环境通常较暗，热缩管往往可以起到颜色识别的作用，尤其是接地线的连接，可以使用黄绿热缩管或者颜色鲜亮的热缩管加以区别，以起到安全标示的作用。
