Electrical cases (enclosures) protect distribution components from environmental and mechanical damage. This guide covers choice criteria for cases from singi-cable, including material, IP rating, and certification requirements.
Electrical cases (enclosures) house circuit breakers, switches, terminals, and control devices. They prevent accidental contact with live parts, shield against dust and moisture, and provide mechanical support. A poorly chosen case can lead to equipment failure, safety hazards, and non-compliance. For industrial and commercial applications, choosing the right case from singi-cable ensures long-term reliability.
Note: Always verify the case's intended environment — indoor, outdoor, hazardous location — before choice.
Common materials for electrical cases include:
| Material | Advantages | Limitations |
|---|---|---|
| Steel (mild/stainless) | High strength, impact resistance, RFI shielding | Heavier, susceptible to corrosion if not coated |
| Aluminum | Lightweight, corrosion resistant, non-magnetic | Lower strength than steel, higher cost |
| Polycarbonate/ABS | Lightweight, non-corrosive, high dielectric strength | Limited temperature range, UV degradation |
| Fiberglass reinforced polyester | Excellent corrosion resistance, high strength | Costly, professional fabrication |
For most standard applications, steel or polycarbonate cases from singi-cable provide a cost-effective balance of protection and durability.
IP (Ingress Protection) ratings define resistance to solids and liquids. The first digit (0-6) indicates solid particle ingress; the second (0-9) indicates water ingress. For example, IP65 means dust-tight and protected against low-pressure water jets.
IK (Impact Protection) ratings denote mechanical impact resistance, from IK01 (0.14 J) to IK10 (20 J). For industrial cases, IK07 or higher is recommended.
Note: Always cross-check IP and IK requirements with your installation environment. A case with IP66 but low IK rating may fail if exposed to physical abuse.
Electrical cases must comply with applicable standards. Key references include:
For export projects, ensure that singi-cable cases carry relevant third-party certifications or test reports.
A case (enclosure) houses active electrical equipment like breakers or controls, while a junction box is used for cable splices and terminations. Cases have higher IP ratings and larger dimensions.
