Product Features:

　　1, compression: PVC plastic electrical sets are divided into light, medium, and heavy three, the catheter in GB / 14823.4-1993 by the pressure test, no visible cracks, it can be installed can also be buried in the concrete , There will be no pressure and damage to the phenomenon.

　　2, impact, heat: PVC plastic electrical casing in the concrete pouring process, by the normal tamping impact will not rupture, in the construction process by the condensation will not become soft (60 ℃ will not be deformed, not loose) The

　　3, acid and alkali: PVC electrical casing will not rust, with excellent moisture and acid resistance, the use of PVC bonding adhesive joints, the better moisture resistance.

　　4, flame retardant: PVC plastic electrical sets in the oxygen content of less than 40% when the non-combustible, and has the self-extinguishing performance from the fire, the level of combustion test up to FH-1 standard, vertical combustion test FV-0 standard Currently the highest level).

　　5, insulation: excellent insulation properties, insulation resistance of not less than 1000 megohm, no breakdown of Mars flash sound show.

　　6, bending flat: excellent bending performance, room temperature to -15 ℃ after bending no visible cracks.

　　7, the construction is convenient: 32mm below the electric pipe sets, inserted in the tube of the corresponding special spring, at room temperature can be arbitrarily bent, wire tube with a truncated pipe can be cut light, with PVC adhesive can quickly and easily The pipe is connected into the desired shape of the construction. Saving more time than steel pipe.
