Technical Workshop: Building Confidence in High-Voltage Cable Operations through Internationally Certified Testing Standards
Fuhrer Wire & Cable Co., Ltd. was honored to welcome Associate Professor Dr. Peera-wut Yutthakovit, a faculty member from the Department of Electrical Engineering, King Mongkut’s Institute of Technology Ladkrabang, along with representatives from the Metropolitan Electricity Authority (MEA) for a hands-on technical training session on AC Withstand Testing and Partial Discharge Measurement—both critical procedures in assessing the quality and […]
Creep Test for Overhead Transmission Conductors
In high‑voltage transmission systems, conductors must withstand long‑term mechanical loads and environmental changes—temperature swings, wind, self‑weight, and ice loading—without developing excessive permanent elongation. Too much creep increases conductor sag, jeopardizing clearances and system safety. The Creep Test is therefore critical for assessing the quality of ACSR (Aluminum‑Conductor Steel‑Reinforced) cables before installation. Test Objectives Test Principle According to The Aluminum Association standard, an ACSR […]
Voltage‑Withstand and Partial‑Discharge Testing
Voltage‑Withstand and Partial‑Discharge Testing for Medium‑ to High‑Voltage (MV–HV) distribution systems—especially underground cables Test Objectives Test Principles 1. AC Withstand Test The cable is subjected to an over‑voltage AC stress (50/60 Hz) significantly above its service rating: 2. Partial Discharge (PD) Test Acceptance Criteria
Underground Wiring System
Underground power cables เป็นสายไฟฟ้าที่ถูกติดตั้งใต้ดินเพื่อนำไฟฟ้าจากสถานีผลิตไฟฟ้าไปยังพื้นที่ที่ต้องการ โดยทั่วไปแล้ว การติดตั้งสายไฟฟ้าใต้ดินมักจะใช้กับพื้นที่ในเมืองที่สูงขึ้น หรือมีที่ดินไม่เพียงพอสำหรับการติดตั้งสายไฟฟ้าบนดิน อีกทั้งยังเป็นวิธีที่ปลอดภัยกว่าการติดตั้งสายไฟฟ้าบนดิน
Service Life of Power Cables & How to Spot Damage
Service lifeInternational‑standard electrical cables typically last 15–20 years. Actual lifespan, however, depends on the environment in which they are installed. Sunlight, heat and moisture can all accelerate ageing. Running the cables inside conduit helps protect them and prolong their usable life. How to Spot Cable Deterioration Routine inspectionHave your wiring checked every 1–2 years. Age‑weakened or damaged cables raise […]
What is Busbar?
A busbar is essentially a common junction point that ties several electrical circuits together. Typically, only a few feeders enter the bar, while many outgoing circuits draw power from it. Because busbars must carry large currents, they are made of highly conductive materials—usually copper or aluminum. The most common profile is a flat rectangular bar, which dissipates […]
