Electric rolling shutter door is very common in life. Because the movement of the door body needs to be driven by electrical equipment, the failure of electrical equipment is inevitable, and leakage is one of them. Then, why does the electric telescopic door leak electricity? Let's follow the example of Fuqiang door industry:

一、马达漏电。受地上平坦度的影响，电机或许在波动的振动下长期运转，增加了损坏电机部件的风险。此外，绕组的绝缘电阻会因潮湿而下降，电机会长期过载，有害气体会被腐蚀，金属异物会侵入电阻，导体的绝缘会被损坏和烧毁，然后导致漏电。

1、 Motor leakage. Affected by the flatness of the ground, the motor may operate for a long time under fluctuating vibration, increasing the risk of damage to motor components. In addition, the insulation resistance of the winding will drop due to humidity, the motor will be overloaded for a long time, harmful gases will be corroded, metal foreign matters will invade the resistance, the insulation of the conductor will be damaged and burned, and then lead to leakage.

二、电缆泄漏。因为线缆需要随着门伸缩支架前后伸展，所以它不能被刚性地维护，而且它常常移动，增加了磨损程度。机械支撑对电缆有必定的机械损伤风险。一旦切断绝缘维护层，...会造成漏电。此外，电缆将长期放置在室外。高温、雨和雾会加快电缆护套的老化。

2、 Cable leakage. Because the cable needs to extend back and forth with the door telescopic support, it cannot be maintained rigidly, and it often moves, increasing the degree of wear. Mechanical support has a certain risk of mechanical damage to the cable. Once the insulation maintenance layer is cut off,... Will cause electric leakage. In addition, the cable will be placed outdoors for a long time. High temperature, rain and fog will accelerate the aging of cable sheath.

在装置和施工过程中，电缆应选用软壳维护，软壳应具有必定的强度，以应对机械损伤。漏电维护器应定期装置和测验。设置合理的行人开口宽度。根据上述情况，电动门预留人行通道的宽度少为0.9-1.2米，为通用人行出口的宽度值。地上应该做好标记，以便给操作者一个准确的提示。

During the installation and construction, the cable shall be maintained with soft shell, which shall have certain strength to deal with mechanical damage. The leakage maintainer shall be installed and tested regularly. Set reasonable width of pedestrian opening. According to the above situation, the width of the pedestrian passage reserved for the electric door shall be at least 0.9-1.2m, which is the width value of the general pedestrian exit. The ground shall be marked to give the operator an accurate prompt.

电动卷帘门的操作地上应平坦，无异物，以削减物理冲击。为了削减漏电事端的产生和防备，咱们应从产品施工和装置的源头入手。施工过程中，厂家应特别注意产品的装置：接地体应设置好，接地引下线不应选用单芯铝线，装置应由有资质的...电工进行。

The operation ground of electric rolling shutter door shall be flat and free of foreign matters to reduce physical impact. In order to reduce the generation and prevention of leakage accidents, we should start from the source of product construction and equipment. During construction, the manufacturer shall pay special attention to the device of the product: the grounding body shall be set well, the grounding down lead shall not use single core aluminum wire, and the device shall be carried out by a qualified electrician.
