CLEAR OPEN 1100X1100MM, C250
In today's increasingly sophisticated communication networks and infrastructure, manhole covers are not only protective facilities but also crucial for ensuring line safety and uninterrupted signal transmission. This 1100×1100mm square SMC communication manhole cover is molded from glass fiber reinforced unsaturated polyester resin (SMC) and is specifically designed for communication, power, and low-voltage network systems. It boasts advantages such as high load-bearing capacity, strong corrosion resistance, and easy installation.
Key Highlights
• Large Square Opening: The 1100×1100mm clear opening provides ample operating space for communication equipment, cables, and maintenance tools, and is compatible with various square manhole structures.
• 12.5-Ton Load Capacity: Rigorously tested, it can stably withstand 12.5 tons of static and dynamic loads, meeting the load-bearing requirements of sidewalks, green belts, non-motorized vehicle lanes, and areas with light vehicle traffic.
• Excellent Durability: Impact-resistant, fracture-resistant, wear-resistant, and with excellent corrosion resistance, it maintains stable structure and appearance even after long-term exposure to rain, moisture, and acidic/alkaline soil environments.
• Safe and Anti-slip Design: The textured surface provides reliable anti-slip performance in rainy, snowy, or wet environments, ensuring the safety of pedestrians and construction workers.
• Convenient Installation and Maintenance: Lighter than cast iron manhole covers of the same size, making handling and installation more efficient; no painting required, minimal maintenance, reducing total lifecycle costs.
• Specifically Designed for the Communication Industry: Provides robust protection for fiber optic cables, cables, and signal equipment, reducing the risk of external interference and damage, and ensuring stable operation of communication networks.
Applicable Scenarios:
Urban communication networks, low-voltage electrical rooms, roadside green belts, sidewalks, and communication wells in residential communities and parks.
