Material properties
Glass steel bridge (high alkali)
Steel bridge
Alloy plastic cable tray
Model specifications
complete

complete
Appearance
Normal (If the hand touches directly, it will cause discomfort)
General (more glitches)
Beautiful (all trays are optimal)
Leakage protection
No need to ground
Need grounding device
No need to ground
Anti-aging
Heat resistance, low wear resistance, long-term high temperature, easy to aging, begin to deform at 50 °C
Easy to rust in wet conditions, short service life
Suitable for use under any environmental conditions, long service life
Temperature resistance
At high temperatures there will be gas du
No harmful substances, but poor thermal insulation
High temperature does not produce harmful substances, has good heat insulation
Oxygen Index
Flammable, oxygen index up to 32 Conventional 20
Product will not burn
Flame Retardant, Oxygen Index Up to 44 and Class I Flame Retardant (The product automatically extinguishes for 1 second from the fire)
Corrosion resistance
The product will not react chemically in i-type crucibles, but it will produce harmful gases at high temperatures.
In the corrosive gas and liquid environment, it is easy to rust and easily corroded
No chemical reaction in corrosive environments
Shielding
No goodBetter (shielded bridge)
On-site changes
Difficult to be easyweight
Lighter and lighterInstallation time
Lock a large number of screws, slow installation (screw holes easily cracked during installation)
Lock a lot of screws, install slowly
No bolting, quick installation
Defective rate at installation
Difficulties in punching at the site, cracks in the bridge itself, and high defect rate
Distortion during handling and installation, high defective rate
Standardized decomposition delivery, on-site installation, low defective rate
When the cable is installed, the bridge structure has no negative effect on the cable
The connected screws may sometimes cause damage to the cables due to incorrect cable pulls, resulting in cracked cables and affecting cable life.
The connected screws may sometimes cause damage to the cables due to incorrect cable pulls, resulting in cracked cables and affecting cable life.
The inner wall is smooth and does not cause cable skin damage when laid (no bolting required)
The role of the bridge when aging the cable
Easy to accelerate cable aging
Easy to form a short circuit with the bridge
Alloy plastic bridge material insulation
