A batch of major innovation achievements are put into use in the machinery industry under pressure

"Since the beginning of this year, under the increasingly complex domestic and foreign development environment, the machinery industry has been under pressure
.

Except for the large fluctuations in individual industries, the economic operation of the machinery industry in the first half of the year was generally stable, and the main economic indicators remained within a reasonable range

The leading role of strategic emerging industries has increased

In the first half of the year, the strategic emerging industries in the machinery industry (117 sub-categories of the national economy) achieved operating income of 7.
73 trillion yuan, a year-on-year increase of 3.
48%, 2.
19 percentage points higher than the overall machinery industry, and in the machinery industry operating income The proportion of 73.
4%, an increase of 1.
56 percentage points over the same period last year
.

Excluding the automotive industry, in the first half of the year, the strategic emerging industries of the machinery industry achieved operating income of 5.

Chen Bin pointed out that since the beginning of this year, the main economic indicators of the machinery industry have been operating at a low level, which has been greatly affected by the decline in the automotive industry
.

Excluding the automotive industry, the 13 sub-sectors of the machinery industry in the first half of the year achieved a total operating income of 6.

The conversion of new and old kinetic energy continues to advance

Under the combined effect of various factors such as policy guidance and market forces, the industry's new and old momentum conversion continues to advance
.

As the main sub-sector of the machinery industry, the automobile industry has continued to weaken since last year, and the decline in automobile production and sales in the first half of this year has continued to deepen

　　In the recent period, under the background of continuous Sino-US trade frictions, machinery industry companies actively respond to changes in the foreign trade environment, strengthen and deepen cooperation with traditional trading partners through multiple channels, and actively expand new trading partners and seek new development.

.

In the first half of the year, private enterprises in the machinery industry achieved a 7.

　　A batch of major technological innovation achievements were put into use

　　In the first half of the year, the Changji-Guquan ±1100 kV UHV DC transmission line developed and constructed by the State Grid Corporation of China, China Xidian Group, TBEA and other units for 6 years successfully achieved full voltage transmission, marking that China has become the world's first.
A country with the ability to transmit tens of millions of kilowatts of electricity within a range of 3000 to 5000 kilometers
.

In the process of implementation, the line first broke through the UHV DC package design, modeling and simulation of the mathematical model of transient voltage distribution in the UHV converter valve tower, high-end converter transformer insulation, and high-performance/large-capacity DC zinc oxide resistors.

　　The 9-bridge 1,600-ton all-terrain crane developed by XCMG Group, XCA1600, successfully completed the installation of 140-meter-high and nearly 90-ton wind turbines at Hebei Baixiang Wind Farm, setting a world record for the installation height of all-terrain cranes
.

During the development process, XCMG has conquered a number of core technologies: one is to build a brand-new boom structure, breaking through the lightweight bottleneck of super-large boom components, and solving the increase in lifting performance of cranes under long boom conditions.

　　In addition, the W12×92 marine crankshaft manufactured by Shanghai Electric Marine Crankshaft Co.
, Ltd.
officially rolled off the assembly line
.

The crankshaft adopts a spliced ​​structure with a total length of 23.
