Industry News - Transformer Aluminum Strip

 

Introduction:

Aluminum strips for dry-type transformers are made of high-quality pure aluminum, which has the characteristics of high conductivity, softness, smooth surface and no burrs. It is an ideal material for the production of dry-type transformers and a key raw material for the manufacture of transformer windings. The requirements for the electrical conductivity, burr curling, side bending, surface quality and other technical indicators of aluminum strip are very high. The application can make dry-type transformers have small size, light weight, good insulation performance, flame retardant, It has the advantages of no pollution, low partial discharge, moisture resistance, stable and reliable operation, low noise, low maintenance cost, etc. It is widely used in high-rise buildings, underground facilities, commercial centers, residential areas, hotels, restaurants and coastal wet areas.

 

Relying on the strong technology and market advantages of the domestic dry-type transformer raw material industry, from the aluminum strip melting and casting process, Sigma strictly controls the melting and casting, rolling, heat treatment, and finished product shearing processes, and optimizes rolling by controlling the alloy composition and the annealing process, so the products have achieved higher electrical conductivity and mechanical properties.

 

Dry-type transformer aluminum strips generally use 1060 aluminum plate and strip, which contains more than 99.6% of aluminum and is also called pure aluminum plate. It belongs to a commonly used series in the aluminum plate and strip family. Advantages of this series of aluminum plates: the most commonly used series, the production process is relatively simple, the technology is relatively mature, and the price has a huge advantage over other high-grade alloy aluminum plates. With good elongation and tensile strength, it can fully meet the conventional processing requirements (stamping, stretching) and high formability. It is industrial pure aluminum, with high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but low strength, and poor machinability; it can be gas welding, hydrogen atom welding and contact welding, not easy to braze; easy to bear kind of pressure processing and extension, bending.
