On October 23, berths at No. 9 Far East Container Terminal in Beilun Port, Ningbo City, Zhejiang Province, with a capacity of 0.3 MW and frequency conversion transformer and 3000 KVA transformers were put in place one after another. This marks Ningbo port smart shore power alternative demonstration project into the electrical construction phase. The project is scheduled to be completed and put into operation by the end of this year, with an estimated annual electricity consumption of about 10.6 million kwh.
Based on the construction of low-pressure marine shore power in Ningbo Port, Ningbo Power Supply Company made every effort to promote the construction of high-voltage shore power demonstration project in Ningbo Port. This year, the company cooperated with Ningbo Port Co., Ltd. to carry out port smart alternative energy shore power demonstration project. Both parties invested a total of about 18 million yuan to build a shore power supply system for high-voltage variable-frequency ship in Ningbo Port Container Terminal and Bulk Port.
Ningbo port intelligent shore power alternative energy demonstration project application of intelligent frequency conversion transformer technology, according to the port by the shore power receiving equipment automatically adjusts the supply voltage and frequency compatible with the current China, Europe, the United States voltage.
In order to fully promote the project construction, Ningbo Power Supply Company tailored the relevant power system plan for Ningbo Port, prepared the project feasibility report, completed the project site selection and initial review. In September this year, the company and the port of Ningbo, equipment supply units, construction units, supervision units set up on-site project department responsible for coordinating the project civil works, equipment construction, electrical testing and other work, timely follow-up project progress and work together to solve the existing problems. After entering the electrical equipment, the company will install two sets of frequency conversion transformer equipment, a total of 5000 KVA power distribution equipment, two sets of static reactive dynamic compensation device, four terminals connected to the electrical box, laying high-voltage cables and control cables A total of 2050 meters.

Needle roller, also known as needle cylinder. A metal cylinder with steel needles planted on the surface. It is installed in the drafting zone for controlling and carding fibers. It is used on spun silk and wool spinning roving frame, carded wool spinning frame, spun spinning and shaft spinning frame. The main body of the needle roller is a copper cylinder with small holes drilled on the surface and steel needles are planted in the holes. Both ends of the cylinder are equipped with a flange, the surface of which is slightly higher than the needle tip to protect the needle tip from damage. The main parameters of the needle roller are: bottom diameter, outer diameter, needle width, needle height, needle density, needle angle and needle number. In order to adapt to the processing of different types of fibers, the small carding roller on the rotor spinning machine has the saw teeth replaced with needles, also called needle rollers.
