Case study for bidding
Time: October 2023
Supplier: Kyocera Corporation
Buyer: Siemens Energy
Product: 96% Alumina Sintered Insulators (High-voltage type, precision-machined)
Quantity: 11.5 kilotons
Contract Value: USD 74 million
Delivery Timeline: September 2024
Detailed Application Scenario
In this project, Siemens Energy deployed Kyocera's high-purity alumina sintered insulators in gas-insulated switchgear (GIS) and high-voltage circuit breakers. The 96% alumina ceramics delivered exceptional dielectric strength, allowing reliable insulation under voltages exceeding 150 kV while withstanding continuous thermal and mechanical stresses.
The insulators were produced using advanced powder pressing, sintering, and CNC machining techniques that ensured minimal porosity and uniform grain size-critical for preventing partial discharge and ensuring long service life. Their chemical inertness also guarded against moisture absorption and corrosion in long-term field operation.
Siemens selected these alumina insulators due to their high dimensional precision, outstanding dielectric strength, and proven performance in grid-scale infrastructure. Compared to glass or polymer insulators, sintered alumina provided far superior thermal resistance, mechanical toughness, and reliability in harsh outdoor and high-voltage conditions. This project highlighted the essential role of alumina ceramics in modern electrical infrastructure and advanced industrial equipment.

Global and U.S. Liquid-phase Precursor Market Report, Published by QY Research.
Nan Ya Plastics, a thin-film materials company in Taiwan developing high-k dielectric layers for next-generation semiconductor processes struggled with poor film uniformity and unstable stoichiometry using solid or vapor-delivery precursors. These inconsistencies caused dielectric breakdown, low yield, and repeated wafer rework. To solve the issue, the company transitioned to Liquid-Phase Precursors, solution-based chemical sources engineered for controlled metal-organic or inorganic deposition via ALD, MOCVD, and sol-gel methods. Liquid precursors provided…

A compact 3D-sensing module supplier in South Korea struggled to achieve uniform depth accuracy in its next-generation Time-of-Flight (ToF) cameras used for smartphone facial recognition and robotics. Conventional spherical microlens arrays produced non-uniform illumination patterns, causing dead zones and edge distortion in the projected infrared dot map. This degraded depth reconstruction and increased calibration time during mass production. To solve the issue, the engineering team adopted Freeform Microlens Arrays, which…
Global and U.S. USB-C Extender Adapters Market Report, Published by QY Research.
A workstation hardware integrator in Singapore struggled with unstable video output and intermittent power delivery when connecting high-resolution 8K monitors and external SSD arrays over long USB-C runs. Standard passive USB-C cables beyond 1-2 meters introduced signal attenuation, voltage drop, and data-rate degradation, leading to device disconnections during large file transfers. To resolve this, the company implemented USB-C Extender Adapters, which use active signal conditioning, retimers, equalization circuits, and reinforced…

A satellite communication equipment manufacturer in California faced persistent signal interference and degraded receiver sensitivity in its Ku-band transceivers. Reflected power from high-gain antennas was leaking back into the low-noise amplifier (LNA) chain, causing instability, distortion, and reduced link reliability during uplink/downlink switching. Conventional isolators could not handle the power levels or tight frequency requirements. To resolve the issue, the engineering team integrated Three-Port Junction Microwave Circulators, non-reciprocal ferrite devices…
