# Industrial Specification: Electrical Feedthrough

## 1. Technical Definition
A sealed component that allows electrical conductors to pass through the wall of a sealed enclosure while maintaining the enclosure's integrity.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1000 VDC, -40°C to +150°C, 0-10 bar differential pressure**. Failure boundary: **Dielectric breakdown at &gt;15 kV/mm electric field strength, seal failure at &gt;20 bar differential pressure, thermal degradation at &gt;200°C**, Mechanism: **Dielectric breakdown via Paschen's law at reduced pressure, elastomer seal compression set exceeding 25% at elevated temperature, metal fatigue at cyclic pressure exceeding yield strength**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in electrical feedthroughs for maximum durability?
**A**: Our electrical feedthroughs utilize premium materials including stainless steel for corrosion resistance, glass or ceramic (alumina) for superior insulation, and copper alloy for optimal conductivity and longevity in demanding environments.

### Q: How do electrical feedthroughs maintain enclosure integrity?
**A**: Electrical feedthroughs feature precision-engineered sealing interfaces and insulator bodies that create hermetic seals, preventing leaks while allowing electrical conductors to pass through enclosure walls without compromising pressure or environmental protection.

### Q: What are the key components in an electrical feedthrough assembly?
**A**: A complete electrical feedthrough consists of conductor pins/terminals for electrical connection, an insulator/seal body for isolation, a metal housing/flange for mounting, and a sealing interface that maintains the enclosure's integrity against environmental factors.

## 6. Manufacturing Compliance
