Abstract
The demand for cable branch boxes is increasing, and some places have special requirements for cable branch boxes. Custom cable branch boxes that meet customer-specific needs need to be tailored, so it is necessary to meet actual requirements. When making custom cable branch boxes, several aspects need to be considered, which is also a prerequisite for ensuring quality. Only with guaranteed quality will customers buy and believe it is reliable. The following details the precautions for purchasing cable branch boxes:Cable Branch Box1. For the grounding circuit of the cable branch box, the maximum short-term withstand current that the grounding circuit should bear is about 87% of the rated short-term withstand current of the main circuit to ensure the safe use of the cable branch box.
2. We should mark a clear and obvious main wiring diagram outside the operation room door of the cable branch box for warning and use.
3. Generally, cable branch boxes should be equipped with a base plate and fire-blocking materials. After installing the cables, the gaps in the base plate should be sealed with fire-blocking materials to prevent moisture from rising in the cable trench and entering the cable branch box.
With the booming development of real estate, the number of cable branch boxes in national grid construction is continuously increasing, and more manufacturers are producing cable branch boxes. According to engineers, cable branch boxes have evolved from the original busbar type with a protection level of IP33 to pluggable, fully insulated types with a protection level of IP67. However, most manufacturers produce cable branch boxes with a protection level of IP33, which are made by small workshops without qualification certificates. So how to choose high-quality cable branch boxes? First, you need to know what materials are used in the cable branch box selected by the manufacturer, such as SMC, plastic, steel plate, stainless steel, and some unscrupulous merchants may use inferior materials as substitutes. Next, observe the thickness of the cable branch box; some manufacturers use thin materials to deceive buyers in order to save costs. Then check whether the surface of the cable branch box is evenly sprayed and whether it has undergone anti-rust treatment. Finally, engineers remind consumers of cable branch boxes not to be tempted by cheap products; they should choose products that are low in price but not at the expense of high cost performance.
随着房地产的蓬勃发展,国家电网建设中电缆分支箱的数量不断增加,电缆分支箱的生产厂家也越来越多,据工程师介绍,电缆分支箱已经从原来的铜排式、防护等级从IP33发展到可插拔、全绝缘、防护等级ip67,而大部分厂家生产的电缆分支箱防护等级为IP33,是一些没有合格证的小作坊生产的。那么如何选择高质量的电缆分支箱呢?首先要知道厂家选的电缆分支箱用的是什么材料,比如SMC,塑料,钢板,不锈钢,还有一些无良商家以次充好,其次,观察电缆分支箱的厚度,有些厂家为了节约成本,用薄料来欺骗卖家。然后要观察电缆分支箱表面是否喷涂均匀,是否进行过防锈处理。最后,工程师提醒需要电缆分支箱消费者不要贪图便宜的产品,要选择价格低的产品,而不是性价比高的产品。
