Advanced crimping demands high performance and high quality
In crimping in advanced applications, such as transformer connections, it is necessary that the crimping system has a high level of performance and is reliable. Elpress has developed a series of products especially for these applications. Together with training of operators, certifications and special products, these form a complete system.
Elpress' crimping system for Transformer connectors contains:
• Joints, such as terminals and through connectors adapted to transformer conductors
• Electrically powered, hydraulic pumps with ergonomic crimping tools, rounding and crimping dies
• Test documentation and certificates as per international standards
• Qualification of production methods
• Training and certification of operators
Elpress' complete system includes connectors from 10 to 630 mm2. They have the suffix L, which is the user's guarantee that the component is a part of the quality assured system.
Special articles have been developed, such as straight and angled T connectors. The marking on the connector shows ID number for crimping tools, metric size, bolt size (for terminals) and make in the form of the logotype. The marking ensures easy and correct use.
With Elpress 13- and 25-tonne crimping heads, simple use is ensured both in the rounding of winding conductors and in crimping. Elpress offers a combined battery and mains-powered and solely mains-powered pump that are both operated using the handle’s buttons.
Rounding and crimping dies are polished to eliminate the risk of sharp edges on the connector.
Elpress has tested the use of terminals and through connectors with the stated winding conductor areas in accordance with IEC61238:1. This is the most accepted standard for electrical connections where the emphasis is on the application's resistive stability after loading. The documentation is available at Elpress.
It is of great importance to have simple methods to ensure the proper use and approved results of the crimping in the course of the work. With Elpress system, an impression is obtained after crimping that shows the crimping dies used. This is a direct and simple method to check that the right tool has been used. For all die sizes, there is a maximum allowed crimping height given that provides an easy check that the tools completed the crimping. The crimping height is measured with sliding callipers.
To ensure that the operators have knowledge to carry out the crimping correctly, Elpress has adapted training containing both theoretical and practical exercises and results in certification of the operators. These individuals receive a qualified level to carry out the work in a safe and proper manner.
When you work with Elpress System for Transformer joints and follow the given instructions for this system, results are obtained that have been tested and verified according to established standards and requirements. This ensures products with a high level of quality.
