ST200 150 A SCR Power Control Cabinet in a Poland Glass Fiber Tank Furnace Drawing Line

Industry: Glass & glass fiber  |  Reference site: glass fiber plant export project in Poland  |  Equipment: power control cabinet with ST200 single-phase SCR power controller 150 A inside

A Kulun Electric power control cabinet is applied in a glass fiber plant export project in Poland, serving heating control of the glass tank furnace fiber drawing section. The cabinet houses an ST200 single-phase SCR power controller rated 150 A, providing stable power regulation for single-phase electric heating loads in the drawing section and meeting glass fiber production requirements for temperature stability, continuous operation and industrial reliability.

1. Project Overview

2. Application Background

The tank furnace fiber drawing section is a key stage of glass fiber production, where stable melting and drawing temperatures must be maintained. The stability of heating power control directly affects drawing continuity, process consistency and production status.

In this export project in Poland, the power control cabinet had to adapt to high furnace temperatures, continuous production and single-phase electric heating loads, and to work with the site temperature control system for stable, reliable heating of the drawing section.

3. Requirements & Technical Challenges

For this application, the heating and power control system had to address the following points:

• High temperature stability requirement: The drawing process is sensitive to temperature fluctuation and needs smooth power output from the cabinet.
• Long continuous operation: Glass fiber lines run in long cycles, so the controller must withstand sustained high-load conditions.
• Single-phase heating load control: The on-site heating circuit is relatively high power and requires stable control from the ST200 150 A single-phase unit.
• Export project adaptation: The cabinet must meet overseas delivery requirements in electrical design, cabinet layout, wiring and maintenance.
• System linkage: The cabinet must coordinate with temperature controllers, PLC or supervisory systems for automated heating control of the process section.

4. KULUN Solution

Kulun Electric supplied a power control cabinet housing an ST200 single-phase SCR power controller (150 A) for heating control of the glass tank furnace fiber drawing section.

The cabinet centrally handles power regulation, protection and field wiring integration for the single-phase heating circuit, and works with the temperature control system to control the drawing section temperature — suitable for continuous heating production in the glass fiber industry.

Key Features of the Solution

• ST200 150 A single-phase regulation. Suits single-phase electric heating loads of the tank furnace drawing section and covers higher-power heating circuits.
• Cabinet integration. Power regulation, protection, wiring and cooling are integrated in one cabinet for easy installation, maintenance and export delivery.
• Smooth, controllable output. Output is regulated by the temperature control signal, reducing temperature fluctuation and keeping the drawing process stable.
• Built for continuous production. Designed for long-running glass tank furnace conditions and continuous high-temperature heating sections.
• Easy temperature control linkage. Works with temperature controllers, PLC or supervisory systems for automated heating control of the drawing section.
• Industrial reliability. Adapts to high temperatures, continuous operation and complex electrical environments of glass fiber sites.
