JYZ Series Busbar Insulator— Willele
Slim, column-type busbar insulators for reliable electrical isolation and compact mounting. Standard Ø14 mm body with heights 14–75 mm, metric threads M4 / M5 / M6 (female or female + stud options). BMC/SMC molding, plated inserts, multiple colors. Ideal for switchgear, PDUs, MCCs, control panels & DC bus systems.
Introduction to Willele JYZ Series Busbar Insulators
The Willele JYZ series is a slim, column-type standoff insulator that provides dependable electrical isolation and mechanical support for busbars in compact cabinets. Each insulator is compression-molded from BMC/SMC with a plated metal insert for repeatable tightening torque, low creep, and long-term stability under vibration and thermal cycling.
Standardized geometry lets panel builders reuse jigs and maintain consistent clearances across Ø14 mm bodies and multiple heights, simplifying layout and inventory.
Why Choose the JYZ Series?
Key Advantages
- Premium BMC/SMC molding delivers high dielectric strength and tracking resistance.
- Rigid plated inserts (brass/steel) for strong pull-out and consistent tightening torque.
- Standard threads M4 / M5 / M6 for straightforward mounting and quick replacement.
- Multiple heights on a common Ø14 mm footprint to match clearance requirements.
- Optional female-female or female + stud configurations; color customization available.
Understanding the JYZ Model Code
The JYZ designation uses a simple pattern: JYZ[Diameter]×[Height]. Standard models use Diameter = 14 (mm). Example: JYZ14×30 indicates a 14 mm body with 30 mm overall height (excluding protruding studs).
Threads are specified separately (M4 / M5 / M6). If you need mixed threading (e.g., one female + one stud), note this when ordering.

Key Features & Technical Considerations
Electrical
- High dielectric strength and insulation resistance for LV/MV systems.
- Material grades available with flame-retardant performance (e.g., UL-style V-0) on request.
Mechanical & Environmental
- Balanced tensile and cantilever strength to resist vibration and short-circuit forces.
- Typical operating range: −40 °C to +140 °C (compound dependent).
- Low water absorption aids long-term dielectric stability in humid conditions.
Applications
- LV/MV switchgear and compact bus ducts
- Control panels and cabinets
- Power distribution units (PDUs) and MCCs
- Renewable/ESS cabinets and DC bus assemblies
- Industrial machinery wiring
- Transportation power systems
Selecting the Right JYZ Insulator
- System voltage: choose a grade whose dielectric withstand exceeds your maximum operating and surge levels.
- Mechanical load: consider busbar mass and short-circuit forces; match the thread and insert material.
- Clearance: pick height (H) to achieve required creepage/clearance distances.
- Mounting: confirm thread (M4/M5/M6) and end configuration (female/female, female + stud).
- Environment: temperature, humidity, pollution degree, UV/chemicals—request special compounds if needed.
