1: The power optical cable product system is becoming more and more perfect

Power optical cable refers to various types of optical cables used for power system communication, and is the optical transmission medium in modern power grids. After nearly 40 years of innovative development and practical application, my country's power optical cable market has continued to grow in size, the technical content has been improved, the power optical cable product system has been improved, and the categories are rich:

Up to now, my country's power optical cables are mainly divided into three types: overhead, non-overhead and underwater. Among them, overhead products include metal OPGW, OPPC, MASS and all-dielectric ADSS, ADSS, GWWOP. Non-overhead products include photoelectric composite OPLC, OPMC; underwater products include photoelectric composite SOPC, etc. Application scenarios: Among them, overhead types such as OPGW are widely used, mainly used to build new lines or replace original ground wires at various voltage levels from low voltage to ultra-high voltage, and OPPC is mainly used for new or old lines of medium and low voltage. Non-overhead cables have insulation requirements and are mainly used for electrical energy, optical signal transmission and access in distribution networks; underwater cables are mainly used for power transmission and communication in offshore wind farms, platforms, islands, etc. The requirements are higher.

From ultra-high voltage, high voltage to low voltage, from land, underwater and ocean, my country's power optical cables have achieved multi-scenario segmentation and coverage, the product system has been gradually improved, and the application fields are broad.

Two: The power optical cable market is positive

The positive development of my country's power optical cable market in 2019, in addition to the increasingly perfect power optical cable product system, also stems from the following reasons:

1. The scale of investment in my country's power grid has increased. The data shows that in 2019, the national power grid project construction completed investment of 485.6 billion yuan, of which the investment in the power grid of 110 kV and below accounted for 63.3% of the investment in the power grid, an increase of 5.9 percentage points over the previous year. Rural power grid upgrading and distribution network construction are the focus of power grid investment, and the power transmission across regions and provinces has grown rapidly. In terms of UHV project investment, in June 2019, my country has put into operation UHV projects with a cumulative line length of 27,570 kilometers and a cumulative substation (conversion) capacity of 296.2 million kVA (kW). Approved the "Three-hands-on-One" project under construction.

2. The two major power grid companies continue to increase the construction of power grid projects. State Grid: In 2019, the State Grid 110 kV and above power grid infrastructure projects started 50,701 kilometers, 293.19 million kVA, and completed 100.13% and 100.17% of the annual plan; 50,752 kilometers and 281.44 million kVA were put into operation, completed. 100.28% and 100.01% of the annual plan exceeded the annual construction task; China Southern Power Grid: In 2019, China Southern Power Grid completed the transformation and upgrading of the rural power grid one year ahead of schedule. The proportion of the two reached a record high. The second round of Hainan's interconnection project was successfully put into operation, actively serving the national regional development strategy, formulating and implementing the company to serve the development of the Guangdong-Hong Kong-Macao Greater Bay Area, comprehensively deepening reform and opening up in Hainan, building a pilot demonstration zone in Shenzhen, and promoting the western region in the new era. The key measures for the large-scale development to form a new pattern.

Summarizing the above two aspects, it is not difficult to see that the expansion of my country's power grid investment scale in 2019, State Grid and China Southern Power Grid continue to complete ahead of schedule or exceed their annual construction goals, etc., all of which have brought certain promotion and promotion to the power optical cable market. Relevant enterprises actively participate in the transformation and construction of UHV power grids, smart grids, and rural power grids, accelerate the construction of a complete industrial chain integrating power transmission and distribution, and help power grid construction and power Internet of Things construction with a complete supply system of power optical cable products, and benefit from it .
