How to choose cable tray ladder
How to choose a cable tray ladder: to choose the right cable tray and ladder, you can refer to how to choose a cable tray ladder as follows:
Use cable tray when is used for thin shielded wires, or in outdoor environments. You should also choose the color that matches the cable type:
Orange cable trays are usually used for control cables.
Gray cable trays are usually used for power cables.
Use cable ladder when is used for sheathed wires such as XLPE or in tunnels, server rooms, where there is air conditioning good environmental conditions.
Based on the characteristics of the wire and the installation location, you can choose cable tray ladder matches the following suggestions:

Classification of common cable tray ladder
Powdered cable tray ladder:
It is a type of electrostatic powder coating on the surface of the material after it has been cleaned and dried through an electrostatic gun that is charged (+) and (-) and placed in a high temperature environment for a long time. The time is 2-3 hours, helping the powder to stick firmly to the surface of the cable ladder and cable tray, protecting the material. Mainly used in houses, basements, parking lots… and is also the most popular type today, with many diverse and rich sizes such as 200×100 cable ladders, 300×100 cable trays, 400×100 cable trays. with or without lid depending on the installation purpose of each unit.
Electro-galvanized cable tray ladder:
Plated in an electrolytic environment, embedded in a zinc bath with negative (-) and positive (+) charges, the electrolytic environment from 2 poles helps the Zinc (Zn) molecules to adhere to the surface of the material. after being washed and cleaned. Their color after electroplating is silver-white, used both indoors or outdoors, they have a good price, so they are used by many electromechanical contractors.
Hot dipped galvanized cable tray:
As the most durable and long-lasting product compared to the rest, after removing surface impurities and drying, they are dipped and a high temperature galvanized bath, with good temperature, helps the Zn elements adhere firmly to embedded materials, they can be used in many different environments such as: sea salt, outdoor, heat-resistant constructions. Hot-dip galvanizing has many advantages, so it is mainly used in key projects, industrial parks…
ZAM corrugated iron cable tray:
As a material with ingredients Zn (Zinc), Al (Aluminum) and Magnesium (Mg) are mixed with the correct composition ratio (Al 6%, Mg 3%), silver color, good corrosion resistance, is not scratched, is applied in many fields, in which the production of cable tray ladders is typical.
Quan Pham Industrial Electrical Equipment Co., Ltd is a leading enterprise in the field of manufacturing cable tray ladders. Currently, we are manufacturing Ladders – Troughs and Cable trays with standard length of 3m/tree.
