Product Overview

Definition: Polyurethane cable conduit box is a rigid structural system used for tightly connecting and supporting cables, mainly made of high-performance polyether polyol composite materials and poly (methyl poly (phenylene diisocyanate) through chemical reactions.

Appearance: It is usually a rectangular groove or box shaped structure, with a smooth and flat surface, mostly in solid colors such as gray white or black, and a simple overall shape that is easy to install and maintain.

Building Materials: Polyurethane cable conduit box.

Product Features

Superior physical performance

● Lightweight and High Strength: Weighing only 1/4 of a steel bracket and about 1/10 of a concrete bracket, it is very convenient for transportation and construction. At the same time, its longitudinal bending strength can reach 720Mpa or more, and it can withstand more cables.

● Good flexibility: The high toughness of polyurethane resin endows the pipe box with good flexibility. When subjected to external forces, it is not easy to undergo brittle failure. Under conditions where the load exceeds its compression limit in a short period of time, elastic deformation will occur, and the shape can be restored after the pressure is removed.

Strong chemical stability

● Good corrosion resistance: It has good chemical stability to atmospheric, water, and general concentrations of acids, alkalis, salts, and other media. It can remain stable in non oxidizing strong acids and a wide range of pH values, with little corrosion on the surface and is not easy to scale.

● Excellent aging resistance: It has strong aging resistance and is not prone to cracking, fading, powdering and other aging phenomena when exposed to outdoor environments for a long time. It can maintain good performance and has a long service life.

Outstanding electrical performance

● Good insulation performance: The bracket has good insulation performance and does not require grounding. The high insulation of the resin combined with flame-retardant composite material avoids the formation of a closed circuit between the magnetic field and the bracket, which can effectively prevent electrical accidents such as leakage and short circuiting.

● Low smoke and halogen-free: produces less smoke and harmful gases during combustion, meeting some high safety requirements and reducing harm to the environment and human health.

Excellent fire resistance

● Heat-resistant, cold resistant, excellent fire resistance, good flame retardant performance, slow combustion speed, smoke density less than or equal to 500, oxygen index above 29, can be used in the range of -40 to 120 degrees Celsius.

Other advantages

● Smooth surface: With a low coefficient of friction, the cable is not easily scratched or damaged during installation and use.

● Good anti-theft performance: Unlike steel cable trays, which have recycling value and are not easily targeted by thieves, it reduces the cost of storage and inventory.

Application Fields

● Power Engineering: Suitable for cable laying of various voltage levels, and can be used for cable support and protection in power plants, substations, distribution rooms, and other places.

● In the field of transportation, it is commonly used in projects such as highways, railways, and urban rail transit. For example, cable conduit boxes on both sides of highways are used to protect communication and power cables, while cable conduit boxes in railway tunnels are used to support and protect signal cables.

● Industrial buildings: In industrial buildings such as factories and warehouses, they can be used to lay power cables, control cables, and communication cables, providing reliable power and signal transmission guarantees for industrial production.

● Municipal engineering: It can be applied to municipal facilities such as cable trenches and cable tunnels in cities to centrally manage and protect cables, facilitating maintenance and repair.
