9th February 2026

The reinforcing core of an optical cable, as the name suggests, strengthens the cable.

Generally, this strengthening effect includes increasing the cable’s radial tensile strength and bending resistance.

The main materials for the reinforcing core of an optical cable include:

Low-carbon galvanized steel wire, aramid fiber, and FRP (fiberglass reinforced plastic) reinforcing core.

Their function is the same: increasing the cable’s tensile strength.

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.
