警示带的分类

Classification of safety warning tapes

警示带的分类：一次性警示带和重复使用警示带、反光警示带、荧光警示带、可探测警示带。

Classification of warning tape: disposable warning tape, reusable warning tape, reflective warning tape, fluorescent warning tape and detectable warning tape.

警示带的材质：PE警示带、涤纶布（相比一次性警示带的优越性：有效克服了一次性警示带使用周期短的局限性，不易拉断、易清洗的简包装方式，集中聚合了盒装警示带的优势，同时，又将盒装的局限性予以改良）

Material of warning tape: PE warning tape and polyester cloth (compared with disposable warning tape, the advantages of disposable warning tape: it effectively overcomes the limitations of short service life of disposable warning tape, the simple packaging method that is not easy to break and easy to clean, centralizes the advantages of boxed warning tape, and improves the limitations of boxed warning tape at the same time)

警示带的用途

Purpose of safety warning tape

管道警示带，广泛地应用于各种直埋式燃气管道、输油管道、城市给排水等气、液管道输送系统、电力电缆、通讯光缆等关于国计民生的第五类运输体系及信息传输系统的警示防护，特别对各种情况复杂的城市管网施工现场、道路施工现场、交通被实验的绝缘胶垫置放骑上，实验电压施加在绝缘胶垫上部的金属极板上。

Pipeline warning tapes are widely used for warning and protection of the fifth class transportation system and information transmission system related to the national economy and the people's livelihood, such as various directly buried gas pipelines, oil pipelines, urban water supply and drainage and other gas and liquid pipeline transmission systems, power cables, communication optical cables, etc., especially for the placement of insulation rubber pads tested in various complex urban pipe network construction sites, road construction sites and traffic, The test voltage is applied to the metal plate on the upper part of the insulating rubber pad.

实验电压从较低值开始上升，并以1000V/s的速度逐渐升压，直达到规定的实验电压或绝缘胶垫发生击穿。实验时间从达到规定的实验电压时刻开始计算。电业持续时间为1min。如实验无电晕发生、无闪络、无击穿、无明显发热，则实验通过。分段实验时，段间的实验边缘应重叠。

The test voltage rises from the lower value and gradually increases at the speed of 1000v/s until the specified test voltage is reached or the insulation rubber pad is broken down. The test time is calculated from the moment when the specified test voltage is reached. The duration of power industry is 1min. If there is no corona, flashover, breakdown or obvious heating in the experiment, the experiment passes. During the segmented test, the test edges between segments shall overlap.
