定义
A specialized component designed to simultaneously provide electrical insulation between conductive elements and create an environmental seal in feedthrough filter applications. It prevents electrical leakage, arcing, and contamination ingress while maintaining signal integrity in high-frequency or high-voltage systems.
工作原理
Operates by creating both a dielectric barrier between electrical conductors and a physical seal against environmental factors. The insulating material prevents current flow between adjacent conductive parts, while the sealing function blocks moisture, dust, gases, or other contaminants from entering sensitive areas.
材料
Typically composed of ceramic (aluminasteatite)engineered plastics (PTFEPEEKpolyimide)elastomers (siliconefluorosiliconeEPDM)or composite materials with specific dielectric strength ≥15 kV/mm and temperature resistance from -40°C to +200°C.
IP Rating
IP67 or higher
Compression Set
≤20%
Temperature Range
-40°C to +200°C
Volume Resistivity
≥10^14 Ω·cm
Dielectric Strength
≥15 kV/mm
Insulation Resistance
≥10^12 Ω
标准
ISO 9001ISO 14001IEC 60601-1UL 94DIN 40050

常见问题

What is the primary function of a seal/insulator in feedthrough filters?

It serves dual purposes: providing electrical insulation between conductive elements to prevent short circuits and creating an environmental seal to protect against contamination, moisture, and other external factors.

How do I select the right material for a seal/insulator?

Consider operating temperature, chemical exposure, dielectric requirements, compression set characteristics, and compatibility with mating surfaces. Common materials include ceramics for high-temperature applications and engineered plastics for chemical resistance.

What maintenance is required for seal/insulator components?

Regular inspection for cracks, deformation, or contamination buildup; periodic replacement based on compression set measurements; and verification of dielectric properties during preventive maintenance cycles.
