Glass fiber reinforced plastic (PRP) optical cable reinforcing core is a product made by curing and pultruding a resin system with glass fiber as the reinforcing material at a specific temperature. It has the following characteristics:

1. It is entirely dielectric, completely avoiding interference from lightning strikes and strong electromagnetic fields.

2. It is lightweight and high-strength; the specific gravity of FRP is about 1/4 that of steel wire, which can reduce the impact of icing and wind, while also reducing the load on towers and supports.

3. It is resistant to corrosion, has good compatibility with other optical cable materials, has a long lifespan, and does not produce harmful gases due to corrosion, thus avoiding hydrogen loss and affecting signal transmission performance.

4. It has a good surface finish, stable dimensions, and is easy to process and lay.

5. FRP is a composite material. To obtain high-quality FRP products, the key lies in the selection of raw and auxiliary materials and the reasonable monitoring of the molding process.

FRP cable brackets (FRP stands for Fiber Reinforced Plastics) are high-quality alternatives to traditional cable brackets made of metal and inorganic materials.

Branch box

This is a distribution sub-panel specifically designed for power systems, serving as a dedicated device for line branching, power distribution, and circuit protection: The box body is made of weather-resistant and anti-corrosion materials (such as SMC composite materials), with a light-colored and simple appearance. It supports various specifications of compartmental structures (such as single door, double door, or triple door), enabling functions like incoming lines, metering, and compensation. The box interior is reserved for component installation, allowing for the installation of circuit breakers, protectors, and other power accessories. The box surface is marked with "Stop! Danger of Electricity" safety warnings and power service logos. It is mainly applicable to power line distribution and management in outdoor, industrial factory areas, and building power distribution scenarios.

Grease trap

The SMC Oil Separation Tank is a high-performance, single-piece molded solution designed for efficient oil-water separation in demanding environments. Constructed from high-strength composite materials (SMC), it overcomes the limitations of traditional concrete or stainless steel tanks, offering superior durability, corrosion resistance, and ease of installation. Ideal for industries handling grease, wastewater, or chemicals, this tank ensures long-term reliability with minimal maintenance.
