1. Compressive resistance: medium conduit and heavy conduit can withstand 750n and 1250n pressure respectively, so it can be installed or hidden in the concrete, not compression rupture, heavy pipe series is especially suitable for use in the concrete needs to tamp and vibration engineering.

2. Anti-impact and heat resistance: the conduit in the concrete pouring process, can withstand normal tamping impact without rupture, and under the action of concrete condensation, will not soften deformation.

3 Flame retardant: has a high oxygen index value, so the catheter is not easy to burn, and from the fire is self-extinguishing, the flame will not spread along the pipeline.

4. Corrosion resistance and insect control: pvc conduit has excellent acid and alkali resistance, will not rust, and does not contain plasticizer, no odor to attract insects and mice, so no insect pests.

5. Insulation: ac2000v and 50hz will not break down under the state of immersion, excellent insulation performance, so it can effectively prevent accidental leakage and electric shock accidents.

6. Convenient construction: It is convenient to cut off the catheter. The corresponding special spring is inserted into the catheter below d32, which can be bent to the required Angle at room temperature.
