Recommended load ≤10T, capable of bearing cable maintenance tool vehicles and light work vehicles, well-matching the daily operation and mild traffic needs of cable trenches;
It has excellent electrical insulation performance, which can reduce the risk of electric leakage in cable trenches and improve operation safety in power laying scenarios.
SMC composite material has strong erosion resistance in humid, mild chemical corrosion environments of cable trenches, with an expected service life of over 20 years under proper use;
The anti-slip surface texture is not easy to accumulate dust and dirt, making daily cleaning and maintenance relatively convenient.
Dual handle hole design allows a single person to open/close the cover easily, greatly improving the maintenance efficiency of cable trenches;
The flat fitting structure can reduce debris falling into the channel, lowering the cleaning cost of cable operation.
Weighing about 22kg (vs. ~45kg for the same-sized cast-iron product), it is easier to install and carry, reducing labor input;
Non-metallic material has no recycling value, which can alleviate the theft issue of traditional cast-iron cable trench covers to some extent.

Clean debris from the cable trench channel and confirm the support frame’s compatibility with the channel;
After placing the support frame, lay the cover aligned with the handle hole direction to ensure it fits the channel;
Conduct a light pressure test to confirm the cover’s stability and check edge gaps (to avoid debris falling in).
Clean surface stains monthly to maintain anti-slip texture effectiveness;
Inspect the cover’s buckle firmness quarterly (focused verification is recommended after the rainy season);
No additional anti-corrosion treatment is required. If damaged, send an email to jschangan111@gmail.com to contact the manufacturer for replacement coordination.
With over 10 years of experience in composite cable trench cover production, its products have passed relevant certifications for electrical insulation performance of power facility materials;
Supports customization of sizes, handle layouts, and logos to meet different cable trench scenario needs;
Door-to-door delivery is available for bulk orders, with supporting installation and operation guidance for cable trench covers.
