Insulation Crepe Paper Supplied to Company in Ukraine
Project Overview
A Ukrainian distributor specializing in electrical insulation materials contacted Chengrui while searching for a more reliable source of insulation crepe paper used in transformer repair and maintenance projects.
The company mainly supplies transformer manufacturers, repair workshops and electrical equipment companies throughout Ukraine and neighboring markets. As demand for transformer refurbishment projects increased, the customer needed a stable supplier capable of providing consistent quality and flexible delivery arrangements.
The project focused on electrical insulation crepe paper used for conductor wrapping, lead insulation and oil channel applications in oil-immersed transformers.
Why The Customer Was Looking For A New Supplier
Before contacting Chengrui, the customer had been purchasing crepe paper from European suppliers.
However, several issues began affecting their business.
Delivery times became less predictable, procurement costs increased, and some batches showed noticeable differences in flexibility and creping structure.
For a distributor, consistency is critical.
Even small variations in paper thickness or creping quality can create problems during transformer maintenance work, especially when technicians need to wrap conductors or insulate irregular-shaped connections.
The customer was therefore looking for a supplier that could provide both stable quality and long-term supply reliability.
Technical Requirements
After discussing the application with the customer, several key requirements were identified.
The crepe paper would be used in oil-filled transformers where flexibility and oil absorption performance are particularly important.
Typical specifications included:
Thickness: 0.05 mm – 0.13 mm
Roll widths: 20 mm – 50 mm
High flexibility for conductor wrapping
Uniform creping structure
Good compatibility with transformer insulating oil
In addition, the customer requested customized slit widths to reduce processing work inside their warehouse.
What Chengrui Did
Chengrui provided sample rolls in multiple widths for evaluation before production.
The samples were tested by the customer's technical team during actual transformer repair work.
Feedback showed that the paper maintained good flexibility during installation and could be wrapped around conductors without tearing or excessive stretching.
The customer also appreciated the uniform roll quality, which simplified inventory management and reduced material waste during workshop operations.
After sample approval, a trial order was arranged for transformer maintenance projects.
Order & Delivery
The insulation crepe paper was supplied in customized slit widths and packed with moisture-resistant protection suitable for international transportation.
Each roll was labeled for easy identification and warehouse management.
The shipment was exported from China and delivered according to the agreed production schedule.
Because the customer regularly serves transformer repair projects, maintaining reliable delivery dates was just as important as product quality.
Project Outcome
Following delivery, the customer confirmed that the material performed well in practical transformer insulation applications.
The consistent paper quality allowed technicians to work more efficiently, while the customized widths reduced additional cutting and handling time.
The successful cooperation led to further discussions regarding other transformer insulation materials, including transformer pressboard, insulation kraft paper and laminated wood components.
For customers involved in transformer manufacturing and repair, stable material quality often has a greater impact than simply achieving the lowest purchase price.
Reliable specifications, dependable delivery and responsive communication remain the factors that create long-term supplier relationships.
