Introduction
Current transformers (CT) are critical high‑voltage electrical components widely used in power grids, electrical meters, industrial control systems, and new energy equipment. To ensure electrical insulation, moisture resistance, dustproof performance, and long‑term operational stability, current transformers require strict epoxy resin potting and encapsulation processing. Traditional manual glue mixing and dispensing cannot guarantee stable mixing ratios, uniform filling, or bubble‑free effects, easily causing insulation failure, partial discharge, and product aging.
A professional two‑component mixing and dispensing machine for current transformer encapsulation is specially designed for CT epoxy and PU potting processes. It provides fully automatic metering, precise ratio control, uniform mixing, and high‑precision fixed‑quantity dispensing, effectively solving common defects in current transformer production and improving product safety and reliability.
Why Current Transformer Production Needs Precision Two‑Component Dispensing Equipment
Current transformer encapsulation belongs to high‑standard electrical insulation processing. The potting glue is usually two‑component epoxy resin or polyurethane material, which must be mixed at an accurate proportion to achieve complete curing, high insulation strength, and anti‑aging performance.
Manual mixing and ordinary dispensing machines have obvious disadvantages:
-
Unstable A/B glue ratio leads to incomplete curing and soft glue
-
Mixed air bubbles cause high‑voltage breakdown and partial discharge
-
Uneven glue filling causes internal gaps and poor heat dissipation
-
Low efficiency, unable to meet mass production requirements
The two‑component mixing and dispensing machine completely solves these problems through servo precision metering, dynamic mixing, and optional vacuum degassing system, becoming the standard automation equipment for current transformer manufacturing.
Core Features of CT Encapsulation Dispensing Machine
Accurate Adjustable Mixing Ratio The machine supports adjustable mixing ratios from 1:1 to 10:1, fully adapting to different brands of epoxy resin and PU potting glue for current transformers. The servo closed‑loop control ensures stable ratio accuracy within ±1%, avoiding batch quality differences.
Bubble‑Free Vacuum Potting Option For high‑voltage current transformers that require ultra‑high insulation performance, the vacuum degassing system removes air from the glue liquid and the product cavity, realizing completely bubble‑free encapsulation. This greatly improves the voltage resistance and safety coefficient of CT products.
Dynamic Uniform Mixing System Equipped with high‑efficiency dynamic mixing valve, the equipment mixes two‑component glue thoroughly without stratification or precipitation, ensuring consistent curing effect for every current transformer.
Stable and Continuous Glue Output Industrial‑grade pumping structure ensures stable glue supply for long‑time mass production, no dripping, no leakage, and no intermittent dispensing, suitable for large‑batch CT factory assembly lines.
