Non-Insulated Cable Terminals Selection Guide: Technical Criteria & Application Standards
Non-Insulated Cable Terminals selection guide: technical parameters, mounting and compliance standards, and Isıso comparison.
A non-insulated cable end terminal is a metal cable end with no plastic sleeve over it, crimped directly onto the conductor and connected under a screw with a ring or fork mouth. It is used in panel, machine and in-device connections where a plastic sleeve is not required or where the connection will be insulated afterward with a heat-shrink sleeve. In this category, Isıso RNB series ring-type and SNB series fork-type non-insulated ends are available in 0.5-1.5 mm², 1.5-2.5 mm² and 4-6 mm² cross-section ranges, in bolt sizes such as M3, M4, M5, M6 and M8. Choose the mouth shape (ring or fork) according to the connection point, the hole size according to the bolt, and the barrel size according to the conductor cross-section. Because the crimp zone stays bare, a non-insulated end does not replace an insulated cable end in connections that sit side by side and need insulation between them, unless an additional insulation sleeve is used. The Non-Insulated Cable Terminals category on Welibaba includes 22 active models from leading manufacturers such as Isıso.
Key Technical Parameters for Selecting Non-Insulated Cable Terminals
To specify the right Non-Insulated Cable Terminals model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Bolt Size | M10, M12, M3, M4 | Verify against project schedule and load calculation |
| Cable Cross-Section | 0.5–1.5 mm², 1.5–2.5 mm², 4–6 mm² | Verify against project schedule and load calculation |
| Isolation | İzolesiz | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Cable Terminals, Lugs and Ferrules.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Bimetal Lugs, Splice Joints, Faston and Connection Terminals.
