High Voltage Switch Parts Line: DTU Assembly and Instrument Transformer Testing Line
Project Overview
This case is designed for manufacturers of high voltage switch parts and distribution automation products. It focuses on DTU assembly, instrument transformer assembly, automated production, and integrated testing.
Taizhou Yufeng Intelligent Equipment Co., Ltd. designs this type of project as a complete manufacturing system, not as a single machine purchase. Workstations, conveyor flow, assembly operations, inspection points, material buffers, safety protection, and future digital upgrades are considered together. For overseas buyers, a visible and repeatable production process is often as important as the equipment itself.
Common Customer Challenges
The customer needed to manage controller assembly, instrument transformer assembly, and testing processes at the same time. Product size is not large, but model variation creates uneven takt time and weak traceability.
When a factory relies heavily on temporary fixtures, manual handling, and experience-based scheduling, production becomes harder to control as order volume grows. Typical problems include unclear workstation responsibility, frequent operator movement, long material waiting time, inconsistent assembly quality, and weak factory presentation during customer audits. A practical production line should make the process easier to understand and easier to repeat.
Yufeng Solution Design
Yufeng connected DTU assembly, instrument transformer production, automated assembly, and testing stations into a fixed workflow. Testing stations are placed near the end of assembly for timely verification.
The solution can be customized according to product dimensions, weight, takt time, process sequence, workshop space, staffing plan, and inspection requirements. Common modules include assembly workstations, belt conveyors, roller conveyors, chain conveyors, overhead conveyors, lifting platforms, pneumatic balance lifts, positioning fixtures, transfer tooling, barcode traceability, work instruction screens, and production data interfaces.
Value for Manufacturers
The solution improves assembly consistency for electrical parts and makes testing records, process management, and factory presentation clearer.
This type of line is especially useful for manufacturers that serve overseas customers and need stable delivery, clear factory presentation, and stronger process control. A well-organized production line helps the sales team explain factory capability more professionally and helps production teams reduce unnecessary handling.
Custom Configuration Options

Suitable Applications
Suitable for DTU, instrument transformers, controllers, electrical modules, high voltage switch parts, and distribution automation products.
Project Summary
A good production line is not a pile of equipment. It is a system that helps a factory build stable manufacturing capability. With proper workstation planning, conveyor design, assisted assembly, and quality control, a manufacturer can reduce unnecessary movement, improve assembly consistency, and present stronger factory capability to global customers.
