Welding mask for Electric power staff

The welding mask is a tool that protects the safety of workers during welding and cutting operations. It is a high-tech product integrating optical, electronics, human science, materials science and other disciplines. The combination of high-quality LCD and plated glass is used as a light-shielding lens. The light-sensing system on the lens can detect the generation and disappearance of arc light during electric welding in an instant, and quickly drive the liquid crystal body to change color and light to achieve safe and effective filtering of harmful light, thus protecting the welder. Eyes and faces avoid arc radiation damage

Earplugs/earmuffs for Electric power staff

Classification and use of earplugs(1) Foam earplugsFoam earplugs can reduce noise by around 30dB, which is best suited to prevent noise from entering the ear. For example, blocking noise on construction sites and blocking snoring while sleeping.However, due to the simple design, wearing foam earplugs can make the sounds heard dull, so this type of earplugs is not recommended for those who want to hear high quality music under noise.(2) EarmuffEarmuff prevent all sound from entering your ear and provide good noise reduction. Using these types of earplugs will mean that you will never hear the outside world.If your job is to operate a large machine, it will emit high-intensity noise, and you don’t need to communicate with others when you work. Wearing a head-mounted earmuff to protect your hearing is very suitable.(3) Silicone earplugsSilicone earplugs have a certain noise reduction function, but in general its main function is waterproof, mainly suitable for swimming, or bathing.(4) High fidelity earplugsHigh-fidelity earbuds refer to music noise-proof earplugs with built-in acoustic attenuation filter that preserves high-quality music while reducing noise, typically reducing noise by around 20dB

Protective gloves against thermal risks(heat and/or fire) for Electric power staff

Protective gloves against thermal risks(heat and/or fire) are also called high temperature gloves, fire gloves, and high temperature gloves. It can be divided into:Protective gloves against thermal risks(heat and/or fire) can be divided by material: carbon fiber asbestos insulated gloves insulated gloves resistant aramid fiber glass insulated gloves insulated gloves, insulated gloves and conventional materials.According to the performance can be divided into: ordinary heat-resistant gloves, flame retardant high temperature insulation gloves, dust-free high temperature insulation gloves, anti-static high temperature insulation gloves, dust-free anti-static high temperature insulation gloves, anti-cutting wear High temperature resistant gloves. The two factors that must be considered when selecting high temperature resistant gloves are: contact temperature and single contact time. These two factors are indispensable. The temperature of the contact object is to consider that the glove material of the contact surface of the glove and the high temperature object does not reflect physically or chemically due to high temperature, for example, burning or carbonic after the ignition point, or oxidation after high temperature. The single contact time is the time to consider when the temperature reaches the inner layer of the glove from the outer surface of the glove and exceeds the temperature that the human hand can tolerate. If you are less than this time in a single contact, then within a safe time frame

Vibration isolation gloves for Electric power staff

Vibration isolation gloves are based on yarn gloves and leather gloves. A certain thickness of foam, latex and air-sandwich synthetic rubber or foam rubber is applied to the palm of the glove to absorb vibration. In winter, the above materials can be added to the winter gloves, and the anti-vibration effect can also be achieved. It can also be used for vibrating workers such as hammer punching or motorcycle drivers. Maiper’s anti-vibration gloves are mainly used for labor protection in operation.

Safety nets for Electric power staff

The safety net is a protective net placed under or on the side of the high-altitude construction equipment installation or performance to prevent accidents caused by people or objects falling. The safety net consists of a net body, border ropes, tie ropes and tendon ropes. The net body is braided from a mesh rope and has a diamond or square mesh. The mesh size refers to the distance between two adjacent knots of the braid. The rope on the edge of the net body is called the border rope. The size of the safety net (nominal size) is determined by the size of the side rope; the rope that secures the safety net to the support is called a tie ropes. In addition, the ropes used to increase the strength of the safety net are collectively referred to as tendon ropes.
