In May last year, the Guangdong Provincial Government issued the “Implementation Plan for the Promotion of the Use of LED Lighting Products in Guangdong Provinceâ€, requiring LED lights to be used in new construction projects in the public lighting sector in the province. The non-LED lighting products originally used in the Pearl River Delta region should be divided before the end of 2013. Batch completed the transformation. According to the requirements, Gaoming District has completed 1877 LED light renovation projects in 5 main roads and more than 200 inner streets in the city last year, involving an investment of nearly 20 million yuan.
Wenhua Road in Foshan City is one of the reconstruction sections. The original 181-seat sodium lamps in the entire section are all converted into LEDs. According to estimates by relevant experts, after the LED lights are modified by Wenhua Road, it is expected to save 265,000 kWh per year, which is equivalent to saving about 93 tons of standard coal, saving 1060 tons of water, reducing 265 tons of carbon dioxide and reducing sulfur dioxide emissions by 7.95 tons, equivalent to planting trees. 2,650 trees were planted, and the electricity bill was saved by nearly 250,000 yuan.
High-voltage 110~220KV XLPE Cable
A. Brief introduction of the 110~220KV XLPE high-voltage cable products
1. The cross-linkage PE insulated and wrinkled aluminum wrapper waterproof PVC Sheathed Power Cable.
Type: YJLW02/YJLLW02
Specification: 240mm²--300mm²
Voltage: 110--220KV
Usage: Suitable for damp areas and the places with a lower underground water level and to be used underground, in tunnels or pipes. Such cables bear a bigger pulling force and pressure.
2. The cross-linkage PE insulated and wrinkled aluminum wrapper waterproof PE sheathed power cable.
Type: YJLW02/YJLLW02
Specification: 240mm²--300mm²
Voltage: 110--220KV
Usage: Suitable for damp areas and the places with a lower underground water level and to be used underground, in tunnels or pipes. Such cables bear a bigger pulling force and pressure.
B. Specific property for usage of 110KV~220KV XLPE high-voltage cable
1. Cable`s conductor highest working temperature is allowed up to 90℃, and overload when meet an emergency is 130℃ ,When short circuit (in ≤5 seconds) the highest temperature is 250℃
2. When installing or laying cable, the ambient temperature should be less than -20℃, and have to give a preheat to cable.
3. The minimum bending diameter:
After laying: 30D0
During laying: 40D0
4. Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral
pressure at bent section) T=K×core NO. ×section (kg), in formula, the coefficient K value should be: the copper core get 7, the aluminum core get 4.
5. Allowed biggest lateral-press P, when cable is being bent
The single core cable is required P≤500kg/m.
P=T/R (T is indicated axial traction force; R is indicated radius of bent-wheel), Knowing from above formula, as the traction force is made up by length and weight of cable. So it lets P to applying requirement as above. Then the diameter of bent-wheel should be widened.
6. Cable laying is not being restricted by drop.
Of course ,except 110~220KV XLPE Cable,we have 500kv XLPE Cable,230kv XLPE Cable, 750v Cable , 132kv Cable , 110kv Cable ect.
