Electrical equipments in modern industrial, commercial and residential users are more sensitive to power quality, and have a higher requirement of quality of power supply. Currently, harmonics,electromagnetic interference, power factor reduction have been tied to the three hazard of the power system.
When it is interfered or contaminated, grid power quality can t reach the national standards, so it has to be targeted on the grid power quality improvement. To understand the actual situation of power quality, you must have the appropriate equipment to test and analysis the actual situation. Counter the domestic condition, our company developed the professional power quality analysis instrument, which is suitable for the country.

PE coil pipes and tubes for water and wire cable conduit PL231
The PE coil pipes and tubes can be used:
water pipe 4 â?? 6 â?? 1-inch black coil with pressure 1.6mpa, OD 20-75mm, WT 2.3-6.8mm
pe conduit cable embedded wire cable and optical cable, OD 20-200mm, WT 1.8-3.5mm
weak current protection tube and communication tube, OD 20-200mm, WT 1.8-3.5mm
We use new 100% pure raw PE material
WHY NEW MATERIAL HDPE PIPES?
1. Health performance
PE pipe processing without adding heavy metal salt stabilizer, no scaling layer, and no bacteria.
2. Corrosion resistance
It can resist various chemical media erosion, with no electrochemical corrosion.
3. Service life
Under rated temperature and pressure conditions, PE pipes can be used for more than 50 years.
4. Impact resistance
PE pipe toughness, high impact strength, heavy objects directly pressed through the pipeline will not break.
5. Connection performance
The strength of the hot melt or electric melt interface of the polyethylene HDPE pipe is higher than that of the pipe body, and the joint will not be broken due to soil movement or live load.
6. Construction performance
It has a lightweight pipe weight, a simple welding process, convenient construction, and a low overall project cost.
