The cable clamp for coal mining machines may be unfamiliar to some. It's not a problem if you're not acquainted with it. Below, the editor will provide some knowledge about the cable clamp for coal mining machines, which can serve as a reference:
Coal mining electrical cable clamps can be categorized by shape into four types: U-shaped, H-shaped, O-shaped, and C-shaped.
The total width of the cable clamp for coal mining machines should match the width of the cable channel used. The height of the cable clamp should correspond to the depth of the cable channel. The internal cavity height of the cable clamp should match the outer diameter of the cable used. The surface of the cable clamp should be smooth and flat, with no exposed steel plates on surfaces covered with non-metallic materials. The cable clamp should be connected in series, allowing for smooth rotation and bending, with the bending angle conforming to the technical drawings.
The arithmetic mean combustion time of alcohol flame for the non-metallic raw material samples of cable clips used in coal mining machines shall not exceed 3 seconds, and the individual combustion time for each sample shall not exceed 10 seconds. The arithmetic mean combustion time without flame for the samples shall not exceed 10 seconds, and the individual combustion time for each sample shall not exceed 30 seconds.
Alcohol Lamp Combustion Performance
The arithmetic mean of the flame combustion time for non-metallic raw material specimens used in coal mining machine cables with a Bunsen burner shall not exceed 6 seconds, and the individual flame combustion time for each specimen shall not exceed 12 seconds. The arithmetic mean of the non-flame combustion time for each specimen shall not exceed 20 seconds, and the individual non-flame combustion time for each specimen shall not exceed 60 seconds.
