The factory started producing synthetic composite insulators.
In November of that year, the Energy Department of the CFMC approved the XWP2-160kN porcelain insulator. This is a high strength, anti-pollution, large creepage distance insulator.

High strength porcelain insulator production lines were finally installed and the factory successfully produced 160kN thru 300kN products. These were used on the first 500KV transmission lines in China – the Pingdingshan, Henan to Wuhan, Hubei line!

The XP-70 and XP-70C products were awarded the “China Electric Porcelain Golden Award.”

The Fourth Technological upgrade was completed  with an investment of 58 million RMB.  The factories were equipped with 530 units of new equipment and machinery.
Included was a new tunnel kiln from the USA, molding/forming  machinery from Germany and other assembly line equipment from Japan. Production capability increased to 5000 Tons per year, part of which included the three most popular porcelain insulators urgently required for transmission lines nationwide.

October. Dalian Electrical Porcelain Central plants were completed with Dalian Electrical Porcelain factory as the  main building, including the steel cap plant, accessory plants, special Porcelain and controlled silica.

D.C. suspension insulators, types XZP-160, XZP-210 and XZP-300 were successfully developed

Insulators for the first D.C. lines in China, Gezhouba Dam to Shanghai, were supplied by Dalian Insulator Co.

Sample testing of the XWP-160, anti-pollution insulator was completed.

After the strategic “Changchun” meeting, the factory began to revise its regulations. It instituted
individual departmental groups again and rebuilt the production directional system.

By this time, management realized it needed to bring the company’s products up to International Standards. It started several material research programs and included Australian and United States Standards such as BS1137 and ANSI. The popular export products XP-70 & XP-70C were put into mass production.
In August of that year, CSEPDI signed a Research Agreement for the development of suspension  insulators capable of handling 500KV cables with a focus on 160kN, 210kN, 300kN and 400kN strengths.

The “Third Technological Reform” program was put into place.

In October, the North East Power Distribution Institute (NEPDI) initiated the “Yuan-Jin-Liao” Project. A 500KV (first time nationwide) technology designed to prove out the most capable and efficient suspension insulator string for this application. The determination was to use both a single string of 28 pcs anti-pollution type XP-160 and a double string of similar type XP-210 insulators. For ground wire insulators, the SDP-70C was chosen.

April. A proposal was advanced to use 160kN anti-pollution insulators to meet the requirements of transmission lines passing through the alkaline soil regions of Panjin, Liaoning Province.
To cross the long stretches through the Liaohe River Delta Marshland, 300kN anti-pollution insulators were proposed.

With improved and increased production equipment and methods, output exceeded a record-breaking 13,000 tons. At this time, annual production increases were almost 50% per year while employee count increased only 10%. Tax revenue to the Government exceeded 22 million, 3 times the original investment by the state. Also, during this year, the central laboratory was renamed the “Research Institution.”

A “Ten Year Plan” for Electrical Porcelain was developed which required increasing overall quality and a complete product line for “less than 220KV.” Further, the Plan called for development of anti-pollution product in the first five years and in the next five years, it called for the development of high strength and small size product.

June. China National Mechanical Equipment Import Export Corp (CMEIEC), Tianjin subsidiary sent staff to Dalian Electric Porcelain..

The beginning of the “Cultural Revolution.” interrupted the regular flow of manufacturing and management authority. It also put an abrupt halt to internal training and technology improvement.

A “Revolution Committee” was established at Dalian Insulator. This eliminated individual departmental groups and established a production directional group, working groups, political and industrial groups and a “support” group. This created an “oversight/leadership” management. This reorganization created a 50% fall-off in production with the resultant negative impact on profits and tax revenue.
October, 1968. An improved “discharge–gap” product, the XDP-70C was approved by the Xi’An High Voltage Switch Research Institution. After that it was put into production.

The Far East Electric Co. was handed over by the Electric Equipment Bureau of the Northeast People’s Government and its name was changed to “Electric Equipment Industrial Management Bureau, 11^th Factory.” The factory ran independently and the factory manager took over full responsibility.

The factory completed its first technology reform.

The First Mechanical & Industrial Department of the Electric Equipment Industrial Management Bureau (called the Mechanical Department thereafter) took charge of the 11^th Factory and its name was changed to “Dalian Electric Porcelain Factory.”

From February to August, part of the Northeast transmission line experienced continuous “flashovers” which caused great concern and losses. In July of that year, according to records of the Northeast Electric Bureau, the Dalian Electric Porcelain factory co-operated with the Dalian Electric Bureau and developed five anti-pollution insulators which were sent to the Northeast Electric Managing Bureau for anti-pollution tests. Dalian Electric Porcelain was the first factory in China to do research and manufacture high voltage anti-pollution insulators.

The factory commenced R & D on 2^nd generation insulators the aim of which was to add new products based on the original II series and to reduce size and weight. According to the Eighth National Congress, Dalian Insulator fulfilled the system of “Factory Director Responsibility and worker’s conference under the leadership of the Party Committee.

The factory built and installed a second “tunnel” kiln. The old downdraft kiln was gradually phased out.

Dahua Porcelain was changed to Shimizu. By this time, with capital of over one million Yen, manufacturing facilities contained 80 automatic and semiautomatic machines.

The two factories reached their highest manufacturing capability of 30,000 tons of fire-proof bricks and 25,000 pieces (1.25 tons) of pin type porcelain electric insulators. Employees now numbered 1800.

After Japan surrendered in August 1945, the Soviet Union sent in army guards to secure Dalian Porcelain and Dahua Porcelain facilities. Workers from the two factories participated as volunteer guards thus, the factories shut down.

Dalian Porcelain and Dahua Porcelain were handed over to the China-Soviet Far East Electric Co. Ltd and were managed jointly by both countries. The two facilities were merged into one company called “Far East Electric Factory.” The Soviets sent in about 10 managing staff as factory directors and other positions to get the factory re-started.

In May, fire-proof brick manufacturing was resumed to be supplied to Dalian Glass factories and Dalian Fire Engines.

In February, the China-Soviet Far East Electric Co. Ltd recruited 30 students from famous technical schools to be placed in various manufacturing departments. This improved the students’ educational level and enhanced their expertise. In April, 90 “porcelain interns” were recruited. After 3 months basic theory study, they were allocated to different departments for actual operation. After 6 years, they were classified and assigned.  These methods provided the company with trained technical personnel. At the end of the 6^th year, the company successfully mass produced high voltage pin type insulators and high voltage suspension insulators and began to export to the Soviet Union.

Dahua Porcelain Company became a division of Dalian Insulator with 80 employees. This company manufactured porcelain accessories such as bowls, plates, teapots, spittoons, ashtrays, etc.

Dahua Porcelain Company expanded to manufacture low voltage telecommunications and pin type electric ceramic insulators. Some military products were also produced such as cannonballs and military flasks.

In July 1925, Dalian Porcelain was formed as another division of Dalian Insulator. At this time, with capital of over 1.2 million Yen, it separated itself from the South Manchuria Railway and began to operate independently. 

A mineral and compound test area was set up in Sakaemachi, Japan with trial production of fire-proofing material such as Porcelain and glassware utilizing raw materials from China such as hard clay from Newxintai Town in Benxi, Magnesia from Dashiqiao, soft clay from the Fuzhou Bay of Dalian, silica from Lushun and coal from Fushun. This pilot plant finally determined future development plans for heat and electrical insulating materials.

A Japanese Company, Shimizu was established in Dalian (predecessor of Dalian Insulator). In the beginning, it was a factory with 200 employees, basically manufacturing heat resistant material such as clay bricks, silica bricks, magnesium stone bricks, refractory clay powder and magnesia powder.

A Japanese company, Shimizu, on behalf of the South Manchuria Railway, built a Test Center in Dalian, China to be responsible for the research of compounds, sanitary products Porcelain, electrical and chemical properties, etc. which lay the foundation for Dalian Electric Porcelain field of study.
