products Introduction

The YJ-AM electrical hazard alarm series products are suitable for working environments with voltage levels such as 220V/380V, 10KV, 35KV, 110KV (66KV), 220KV, 500KV, etc. You can also customize voltage level products according to customer needs.

Applicable scope:

This product is a safety auxiliary product that can be installed in a safety helmet or carried for use. It is mainly suitable for construction and maintenance personnel in power lines, power generation and distribution, communication, railways, buildings, and other places.

Product features:

1. Adopting a self-developed specialized chip with built-in analog digital dual filters, it has strong anti-interference ability, high sensitivity, stable alarm distance, and fast response speed.

2. Equipped with dual self check function when starting and shifting gears, reducing the probability of misoperation and improving work reliability.  

3. The product has extremely low power consumption and uses a button battery, which can be used for about 3 years.

4. The shell is made of high-quality ABS material, which is sturdy, durable, small in size, and lightweight. It can be installed with built-in double-sided adhesive or with a dedicated bayonet inside the safety helmet, making disassembly and assembly convenient.

5. Operating temperature range: -20 ℃~+55 ℃, alarm volume: ≥ 90dB.

The alarm distance is shown in the table below

Note: The alarm distance refers to the distance measured under the overhead line after the warning device is installed in the safety helmet and worn by the user. When using the 220V gear to detect the 220V power supply wall switch, due to the electric field being absorbed by the wall, the alarm distance is around 0.03m~0.06m (only used for calibration at this time).
