Zheng Liyao: The growth of output value of LED lighting industry will slow down in the next three years
Lin Jili, general manager of Mulinsen Lighting, Yang Lixin, deputy general manager of Yuanda Electronics, Wen Kongliang, director of overclocking technology engineering, Zhou Xunwei, general manager of Jiehuate Electronics, Zhang Zhennan, R&D manager of Jingtai Optoelectronics, Li Sheng, general manager of testing and testing, etc. Share from the sub-areas of light sources, power supplies, substrates, cooling kits, and finished product inspection.
Zheng Liyao, general manager of Gaogong LED, pointed out in the keynote speech of “2014 LED Industry Development Forecast†that it is subject to the macroeconomic environment, especially the real estate (residential and commercial real estate) market fluctuation, the rapid decline of product prices in all links of the industrial chain, and the LED lighting output value base. The growth rate of the industry's output value will slow down in the next three years due to factors such as rapid growth and low-cost channel effects such as e-commerce.
Gao Li LED General Manager Zheng Liyao
In this context, how should companies respond? Zheng Liyao proposed: First, we can extend the product line horizontally and open up new market segments. Second, reorganize and merge other existing enterprises or squeeze them out of the market. Third, accelerate the replacement frequency of products through the enterprise's own trade-in; fourth, Systematic transformation of the marketing system, in addition to traditional channels, when focusing on mobile Internet, O2O and other emerging channels; Fifth, improve product premium capabilities.
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.
