Hengtong's coated lead extrusion machine enters dry run test
Mar 05 , 2020

After the resumption of work, the first batch of lead extrusion machines were shipped, and another batch of coated lead extrusion machines entered the dry run test. Jiangsu Hengtong Optoelectronics Co., Ltd., the subscriber of this batch of lead extrusion machines, is one of the core companies of China Hengtong Group Co., Ltd. It is a joint stock company specializing in the production of various optical fiber and cable products.


In 2016, Jiangsu Hengtong High-voltage Submarine Cable Co., Ltd. achieved a major breakthrough, overcoming a number of worldwide technical difficulties such as cleanliness control of ultra-high-voltage materials and ultra-thick insulation extrusion processes for 500KV cross-linked submarine cables, and passed the type tests of professional and authoritative testing institutions. At present , 500KV submarine transmission is the highest voltage level for submarine cable transmission. In November 2019, Hengtong Optoelectronics announced that the company and Huawei Technology Investment Co., Ltd. signed the "Issuance of Shares and Payment of Cash to Purchase Assets", and Huawei Ocean became a 51% -owned subsidiary of Hengtong Optoelectronics. In the future, Hengtong plans to acquire 100% of Huawei Ocean. After the acquisition of Huawei Ocean by Hengtong, it will undoubtedly change the competitive environment of the domestic submarine cable market.

As a partner of Hengtong, ITO-SIN is also constantly improving the quality of its services and products, and strives to stand out from the competition. Submarine cables have been running underwater for a long time, so the radial water blocking performance is particularly important. The lead sleeve is completely impermeable, can reliably prevent the intrusion of moisture, and has good sealing performance; the lead sleeve also has the advantages of corrosion resistance, simple lead-pressing process, and good toughness. The coating lead extruder is used for cable covering lead sheath and rubber tube covering lead vulcanization, and supports long-term continuous and stable production of lead sleeve.
