The Eaton XJG28 HDG XJG expansion coupling is designed for use with EMT, rigid metal conduit, and IMC. Its primary function is to connect two sections of conduit that are subject to longitudinal movement. This movement, often caused by thermal expansion and contraction, can damage conduit supports and electrical systems in structures like buildings or bridges. The XJG28 HDG model features a hot-dip galvanized finish, providing enhanced corrosion protection against environmental factors, particularly for trade sizes 1-1/4 inches and above.

Bezpečnostní informace
Always follow local electrical codes and regulations during installation. Ensure power is disconnected before working on electrical systems. Use appropriate personal protective equipment (PPE) such as safety glasses and gloves. Installation should be performed by qualified personnel.
Nastavení a instalace
- Zkontrolujte komponenty: Before installation, verify that all components of the XJG28 HDG expansion coupling are present and undamaged.
- Příprava konců trubek: Ensure the ends of the EMT, rigid metal conduit, or IMC are clean, free of burrs, and cut squarely.
- Determine Expansion/Contraction Range: Calculate the expected longitudinal movement due to thermal changes. The coupling is designed to accommodate this movement.
- Position Coupling: Insert the conduit ends into the coupling. The coupling should be positioned to allow for the full range of anticipated expansion and contraction.
- Zabezpečená připojení: Tighten the compression fittings or set screws (depending on coupling type) securely to ensure a proper electrical and mechanical connection. Do not overtighten.
- Ověřte zarovnání: Ensure the conduit sections are properly aligned within the coupling to prevent stress on the system.

Provozní principy
The XJG28 HDG expansion coupling operates passively by allowing the conduit sections to slide within its body. This mechanism absorbs the forces generated by thermal expansion and contraction, preventing these forces from being transferred to conduit supports, junction boxes, or other electrical components. The hot-dip galvanized finish ensures the coupling maintains its structural integrity and corrosion resistance throughout its operational life, even in harsh environments.
Údržba
- Pravidelná prohlídka: Regularly inspect the coupling and surrounding conduit for signs of wear, corrosion, or damage. Check for proper alignment and secure connections.
- Čistota: Keep the coupling free from excessive dirt, dust, or debris that could impede its movement or compromise its finish.
- Environmentální faktory: In highly corrosive environments, more frequent inspections may be necessary to ensure the integrity of the hot-dip galvanized finish.
- Není nutné mazání: The design of the coupling typically does not require lubrication for its expansion and contraction mechanism.
Odstraňování problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Conduit movement restricted | Improper installation; debris in coupling; overtightened fittings. | Verify correct installation according to manufacturer guidelines. Clean coupling. Loosen fittings slightly if overtightened, then re-secure to proper torque. |
| Signs of corrosion | Damage to galvanized finish; extremely harsh environment. | Inspect the finish. If minor, clean and apply a suitable cold galvanizing compound. If severe, consider replacement. |
| Conduit separation from coupling | Fittings not tightened sufficiently; extreme movement beyond design limits. | Ensure fittings are securely tightened. Re-evaluate the expected movement range and ensure the correct coupling size is used. |
