Increased degree of smart grid and ultra-high voltage industry

According to relevant plans, the State Grid planned to invest 318.2 billion yuan in power grids in 2013, an increase of 4.2% year-on-year, maintaining a stable trend. Market participants pointed out that there are obvious differences in the opportunities of the sub-industries of the power grid in the incremental, specifically, the smart grid, ultra-high voltage and high-pressure industries have a higher degree of prosperity.

According to analysis by Hang Seng Securities, the new energy industry for power equipment is the most intensive area among the seven emerging industries. Therefore, in the medium term, the power equipment industry will emerge as a beneficiary company for emerging economic models, such as hydropower in a booming cycle. , energy-saving environmental protection areas, distributed energy equipment such as waste heat boilers, gas turbines, etc.

“But more specific opportunities are still concentrated in the two sub-sectors of smart grids and ultra-high voltage transformers.” Zhang Peng, an analyst at Zheshang Securities, told reporters on the one hand that there are technological systems for building smart grids and building smart cities in many cities. Natural integration, based on the integrated collaborative application of the Internet of Things, cloud computing and broadband converged communication technologies, will have a profound impact on the city's intelligence on the basis of ensuring reliable supply of energy. With the gradual improvement of smart grid infrastructure construction, large-scale construction of smart cities is expected to start. On the other hand, the ultra-high voltage changes on the whole have a very important role in changing the current status of China's current uneven distribution of power resources and achieving long-distance transmission.

Looking specifically at the sub-sectors, the overall gross profit of the primary equipment segment of power transmission and transformation is at the bottom. The secondary equipment sector has benefited from smart grid construction, with the overall performance and stock price trend being the strongest among the segments. Since the first two batches of cases of centralized bidding for power transmission and transformation equipment in the State Grid have seen a significant increase in the amount of tenders for secondary smart equipment year-on-year, investors can focus on industry leaders and subdivision leaders with strong orders and certainty in this area.

Self-Expanding Packer

Structure: Made up of oil expanding type or water expanding type expandable elastomer material, mechanical pipe string, centralizer and ect. 

Usage:

1. Segregated completion: Horizontal well/large displacement well can be interlayer-packed to carry out sub-level exploitation;

2. Packing water bearing layer: pro-phase and anaphase water plugging operations can be carried out to cut off the water bearing layer with good plugging effect;

3. Separate-zone production:oil well can be interlayer-packed according to its producing layer to improve the protection;

4. Assisting well cementing: it can be used at the top and bottom of the casing to provide supplementary packing after the well cementing in case of the problem of channeling because of the bad cementation between the cement ring and the casing, guaranteeing the tightness and improving the cementing quality;

5. Simplifying the well cementing: with the simple construction technology, the well completion technology can be simplified and the well construction period can be shortened;

6. Sectional development of the reservoir: after development, oil production can be put into quickly without moving the pipe string. 

7. Intelligent completion: intelligent completion can be carried out together with slide bushing and other tools

8.Sand protection: provide the top mortise packing for horizontal gravel filler. 


Specifications:
1. ISO 9001/ API Q1 / ISO14001 / OHSAS 18001 Certificate
2. Large stocks Timely delivery
3. Professional
4. Good after-sale service
