Basic Knowledge of Cable Conductors

Cable tray, categorized by material

① Glass Fiber Reinforced Cable Trays; ② Polyurethane Cable Trays; ③ Composite Epoxy Resin Composite Cable Trays (Abbreviated as CRC Trays)

④ Steel cable tray (divided into: hot-dip galvanized cable tray, electrostatic spray paint cable tray, etc.);

Cable bridge supports, hot-dip galvanized painted cable bridge supports, galvanized steel cable bridge supports, fire-retardant paint coated cable bridge supports, etc.

2. Cable tray type:

Slot type: Also known as holeless tray type. Represented by the letter "c."

②

Ladder style: Also known as ladder step. In alphabetical letters:

"Indicate."

③ Tray-style: Also known as perforated trays. Represented by the letter "P."

④ Slot-type: Also known as slot and base type. Represented by the letter "TC."

3. The manufacturing process of glass fiber reinforced cable trays is divided into two

Extrusion process

SMC Process

4. Bridgeway specification representation method

Width x Height x Length. Unit: mm

GFRP槽形 cable tray, 200*100*600mm, made of glass fiber reinforced plastic, with a槽-shaped design.

A cable bridge with a height of 100mm and a length of 6000m, rated for 200m.

Steel cable tray

1. Glass-Fiber Reinforced Plastic (GFRP) Bridge Trays Styles:

⑦FRP channel cable tray, commonly known as glass fiber reinforced plastic cable channel, is a one-time pultrusion-formed product.

② The glass steel ladder-type cable bridge is assembled from individually produced ladder bands and ladder oranges.

③ The ladder slot type is formed by adding a bottom plate to the ladder design, combining the strength of the ladder with the enclosed nature of the slot.

④ The tray-type (pierced tray) is formed by creating staggered holes in the bottom of the channel-type slot.

2. Characteristics of fiberglass bridge beams:

Use.

High corrosion resistance. Capable of withstanding strong corrosive environments such as acids and alkalis, as well as humid conditions.

② Excellent flame retardancy, anti-static, and non-conductive properties.

③ Excellent aging resistance and long lifespan: No recycling value, not easily discarded.

④ Lightweight, easy to cut, install, and process for non-standard shapes.

3. FRP Cable Tray Manufacturing Process: The FRP cable tray is manufactured through pultrusion

Process: fibers yarns impregnated with resin after being treated with alkali-free, untwisted, and unwaxed fibers, then subjected to high temperature

Produced by curing and shaping from molds. Among them, an appropriate amount of aluminum powder is added, serving to...

Lightweight and flame-retardant properties.
