Description

• Integrated Nine-Hole Grid Structure The monolithic extrusion design creates nine independent internal channels, eliminating the need to manually insert sub-ducts during installation. This structural integration maximizes space utilization within the utility trench, allowing contractors to consolidate multiple cable lines into a single conduit footprint and reduce the overall excavation volume.
• Enhanced Wall Thickness and Compression Resistance With a reinforced outer wall of 2.2mm and inner walls of 1.2mm, the square grid geometry provides a distributed load-bearing framework. This specific design ensures that the pipe maintains its cross-sectional integrity under soil pressure and heavy surface traffic, preventing duct deformation that could otherwise obstruct future cable pulling or replacement.
• Advanced Dielectric and Corrosion Properties Manufactured from high-grade PVC, this conduit functions as a reliable electrical insulator for power distribution systems. The material's natural resistance to chemical corrosion and soil-borne moisture prevents degradation in acidic or alkaline environments, ensuring the long-term safety of the encased cables without the risk of galvanic corrosion or conductive failure.
• Low-Friction Smooth Interior Surface The interior walls of each grid hole are finished to a high degree of smoothness to minimize the coefficient of friction during cable installation. This reduction in pulling tension prevents damage to sensitive cable jackets and allows for longer continuous cable runs between manholes, thereby reducing the number of splices required for the project.
• Modular Square Profile for Stackability Unlike standard circular conduits, the flat-sided square design enables stable, organized stacking without the risk of rolling or shifting during backfilling. This modularity ensures precise alignment across large-scale conduit banks, simplifying the engineering layout for complex multi-system telecom and power intersections.
• Broad Operational Temperature Tolerance The PVC compound is engineered to maintain its mechanical properties across a temperature range of -40°C to +80°C. This thermal stability ensures the pipe remains impact-resistant in cold climates and retains its structural rigidity in tropical underground conditions, making it a viable solution for diverse global geographic regions.
• Simplified Socket Connection System The standardized square socket joints allow for rapid, secure alignment of pipe sections without specialized welding equipment. This simplified joining method accelerates the construction timeline and reduces specialized labor requirements, contributing to lower total project costs for large-scale municipal roadworks.
• Integrated Flame Retardancy The inherent self-extinguishing properties of the PVC material provide a critical safety layer in electrical communication systems. In the event of an internal cable fault or external heat exposure, the conduit inhibits the spread of fire along the underground network, protecting adjacent infrastructure and reducing the risk of extensive system downtime.

Scope of application

• Engineering Application Scenarios for PVC Porous Grid PipesThe PVC Porous Grid Electric Square Pipe is engineered to meet the rigorous demands of underground cable management. Its multi-hole design and square profile are specifically optimized for projects requiring high-density cable routing and long-term structural reliability.
• Municipal Power Grid ModernizationThis PVC grid pipe is extensively used in urban underground power network upgrades to replace aging overhead lines. It serves as a protective conduit for low-to-medium voltage power cables beneath sidewalks and non-motorized vehicle lanes. The PVC-U material provides excellent electrical insulation and resistance to soil-borne corrosive agents, ensuring stable operation within a standard ambient temperature range of -40°C to +80°C.
• Telecommunications and 5G Backbone InfrastructureIn the telecommunications sector, the 9-hole PVC honeycomb conduit is the standard solution for protecting high-core-count fiber optic cables along metropolitan area networks (MANs). The integrated sub-duct structure allows for the physical separation of cables from different service providers within a single trench. Its smooth interior surface reduces friction during high-speed cable blowing or pulling, preventing attenuation losses in sensitive optical fibers.
• Industrial Park Integrated Utility SystemsFor large-scale industrial zones and data center hubs, these multi-hole electrical conduits are deployed to manage complex cabling for automated control systems and power distribution. The square design allows for stable, multi-layer stacking in utility tunnels, accommodating high-load cable densities without compromising heat dissipation. The high-impact resistance of the 2.2mm outer wall protects internal wiring from mechanical vibrations common in industrial environments.
• Highway and Transportation Signal ManagementThis PVC porous grid pipe is applied in the construction of intelligent transportation systems (ITS) for housing power and data lines for traffic signals, surveillance cameras, and tolling systems. Its rigid grid structure ensures that the duct remains clear and accessible even under the dynamic loads of roadside soil. The flame-retardant properties of the PVC material provide an essential safety barrier, preventing localized electrical faults from spreading along the highway infrastructure.
• Smart Residential and Commercial Real Estate DevelopmentDuring the primary construction phase of modern residential complexes and commercial plazas, these integrated square pipes are used to organize the underground "last-mile" connectivity. They house a variety of low-voltage systems, including building automation, fire alarms, and high-speed internet. The ease of socket-based installation significantly reduces the construction timeline in dense urban sites where excavation windows are strictly limited.
• Long-Distance Communication Trunk LinesIn cross-regional projects, the PVC porous grid pipe is utilized for long-haul transmission of telecommunication signals through diverse geological conditions. Its chemical stability makes it suitable for direct burial in marshlands or coastal areas with high salinity. The consistent wall thickness and interlocking joints ensure a continuous, watertight protection barrier that maintains the integrity of communication lines over extended service life.

Engineering Notes for Project Selection

• Suitable Environments: Ideal for direct burial in soil, installation in utility tunnels, and embedding in concrete structures where chemical resistance and dielectric strength are required.
• Not Recommended For: This product should not be used as a structural load-bearing beam or in high-pressure fluid transportation systems. It is strictly designed for the protection and management of non-pressurized electrical and communication cabling.
