Product Parameters
Product Overview
Usage Environment
Ambient temperature: -45℃~150℃℃
Ozone concentration: *100ppm
Humidity: 0~100%
Protective shell bearing weight: *5kg
Flame-retardant expansion material and flame-retardant sponge
Flame-retardant expansion material is a solid flat plate, which expands when heated (temperature 160℃),
Expansion ratio>500%, after preheating and expansion, its shape changes to flocculent material, and forms a completely
Incombustible carbon layer. The flocculent material formed by expansion will wrap around the cable surface, fill the gap between the cable and the metal
frame, and achieve flame retardant function.
Metal structural parts
Use 2mm galvanized sheet
Surface sprayed with fire retardant paint
Technical standards
Comply with the following standard documents:
GB 50217-2018
“Electric Power Engineering Cable Design Standard”
GB 50872-2012
“Hydropower Engineering Design Fire Protection Code”
GB 23864-2009 “Fireproof Sealing Materials”
In the early stage of fire, when the temperature rise does not reach 160℃,
the fireproof cloth arranged on both sides of the fire-blocking section can
prevent the flame from transferring to the other side (back of fire), thus achieving the function of blocking the initial fire.
