Product OverviewRecommended load ≤10T, capable of bearing cable maintenance tool vehicles and light work vehicles, well-matching the daily operation and mild traffic needs of medium-sized cable trenches;
With insulation resistance ≥10¹²Ω, it has excellent electrical insulation performance, which can reduce the risk of electric leakage in cable trenches and improve operation safety in medium-sized power laying scenarios.
Single handle hole design allows easy opening/closing by one person, improving the maintenance efficiency of medium-sized cable trenches;
Anti-slip cross texture + flat fitting structure not only reduces the risk of slipping for pedestrians/vehicles but also reduces debris falling into the channel, alleviating operation cleaning pressure.
SMC composite material has decent erosion resistance in humid, mild chemical corrosion environments of medium-sized cable trenches, with an expected service life of over 20 years under proper use;
The surface material is not easy to attach dust and light oil stains, making daily cleaning and maintenance relatively convenient.
Weighing about 25kg (vs. ~50kg for the same-sized cast-iron product), it is easier to install and carry, reducing labor input for medium-sized cover operations;
Non-metallic material has no recycling value, which can alleviate the theft issue of traditional cast-iron medium-sized cable trench covers to some extent.

Clean debris from the medium-sized cable trench channel and confirm the size compatibility of the support frame with the channel;
After fixing the support frame, lay the cover smoothly aligned with the handle hole direction to ensure it fits the channel edge;
Conduct a light pressure test with a light work vehicle to confirm the cover’s fitting stability.
Clean dust and light oil stains from the cover surface 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 medium-sized composite cover production, its products have passed relevant certifications for electrical insulation and light-load scenarios of power facilities;
Supports customization of sizes, surface textures, and logos to meet different medium-sized cable trench scenario needs;
Delivery service + basic installation guidance are available for bulk orders, ensuring the operation efficiency of medium-sized covers.
