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

Better (shielded bridge)

On-site changes

weight

Installation 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
