PE (polyethylene) material is widely used in the field of water supply pipe manufacturing because of its high strength, corrosion resistance, non-toxic and other characteristics.
Because it does not rust, it is an ideal alternative to ordinary iron pipes. PE water supply pipe Implementation product national standard: GB/T 13663.1-2017, GB/T 13663.2-2018 polyethylene (PE) Pipeline System for Water Supply part 2: Pipe.
Crosslinked PE Pipe(Crosslinked Pe Pipe) using the first domestic co-extrusion irradiation technology, making the visible light barrier layer and ultraviolet absorption layer co-extrusion in the tube.
The Pex Cross Linked Polyethylene can avoid the aging phenomenon caused by exposure to ultraviolet rays in the atmosphere, which in turn improve the service life of the pipe.

The new high-pressure sodium lamp electronic ballast adopts advanced technologies and materials such as IC circuits and high-frequency magnetic components in modern microelectronic technology to carry out the best performance and high reliability design, energy saving and environmental protection. Its power factor is greater than 0.98, the output power is constant, the illumination is constant, and the electro-optical conversion efficiency is improved. EMI has low electromagnetic interference, excellent performance and high performance and price ratio.
The project's products are carefully designed with advanced foreign technology and have superior characteristics that traditional inductive ballasts cannot match. The performance parameters of the two products are compared as follows:
Project electronic ballast inductance ballast
1. Rated input voltage 220V/50Hz 220V/50Hz
2. Applicable voltage range 160V~265V/50Hz 198V~230V/50Hz
3. Power variation (%) 160V~265V: ±1.5% 160V~260V: > 50%
4, power factor λ ≥ 0.98 0.65 (with capacitor compensation 0.8)
5, third harmonic ≤ 7% > 17%
6, starting current (A) ≤ 0.6 3.8 ~ 4.5
7, the efficiency of electro-optical conversion
8, noise (1 meter) / moderate amount
9, efficiency 95% 50~60%
10, the working current is about 1A about 3A
11, the lamp life of more than 3 years, the replacement rate of 87%
The characteristics of the electronic ballast can be seen from the above main technical performance tables:
1. High power factor: ≥0.98, the real best transmission of grid power, in addition to heat loss, almost 100% output to the load, reactive power only accounts for a few percent, which is its main energy-saving mechanism. When the power factor of the inductor ballast is 0.65, the active power only accounts for 65% of the input power, and the reactive power accounts for 76% of the input power.
When λ=0.85, the active power accounts for 85%, and the reactive power accounts for 52.6%;
When λ=0.995, the active power accounts for 99.5%, and the reactive power only accounts for 10%.
Electronic ballasts can maximize the use of grid power supply capacity, reduce grid losses, and the reactive power of the ballast ballast is too large, increasing the reactive load of the power plant and increasing the grid loss.
2, constant power output:
When the grid voltage changes from 160V to 265V, the ballast output power is basically constant, the change is less than 1.5%, that is, the 250W high-pressure sodium lamp power variation is less than 3.75W, so that the high-pressure sodium lamp adapts to the grid change with the best state and performance. Effectively ensure the stability and balance of illumination. On the contrary, the inductance ballast power variation of 27% (under constant current performance under high pressure sodium lamp) greatly affects the lighting effect and shortens the life of the high pressure sodium lamp.
3, low-voltage starting performance is excellent, to ensure that lighting is not affected by the power grid settings. Inductive ballasts can only be normally started and lit in the range of 90% to 105%.
4, ultra-wide voltage adaptation range: 160V ~ 265V, especially suitable for long distances such as highways and other power supply occasions.
5, no low frequency noise, reduce environmental noise.
6, electromagnetic interference school
7. Since the working frequency of the electronic ballast is about 30KHz~45KHz, the electro-optical conversion efficiency of the high-pressure sodium lamp is improved, and the electric energy is saved under the condition of the same illumination, and the service life of the lamp tube is prolonged.
