Quick Details
Place of Origin: Guangdong, China (Mainland)
Brand Name: BSUMWELL/OEM
Model Number
busbar insulator
Name
electric busbar insulator
Insert:
brass,steel aluminum
Core Features
Multiple Models for Versatile Needs: Covers SM20-SM100 (plus SM-7100/7105 etc.) with varied specs—diameter 18-65mm, height 20-100mm, thread M5-M12. Adapts to different busbar sizes and installation spaces in electrical equipment.
Durable Material Combination: Made of unsaturated polyester resin + glass fiber (high-temperature pressed) for flame retardancy and pressure resistance; brass thread ensures secure, corrosion-resistant connections, avoiding electrical faults.
Excellent Electrical & Mechanical Performance: High insulation strength to prevent leakage; low voltage (220V rated, up to 660V compatible) safe for residential/commercial use. High hardness, no fracture at low temps, no deformation at high temps.
Reliable Structural Design: Red color for easy identification; brass inserts with good thermal conductivity improve heat dissipation. Strict quality control (ISO/CE certified) ensures each product meets safety standards.
Customizable Options: Supports logo, packaging, and graphic customization (MOQ 10,000PCS) to match project or brand needs, with flexible technical adjustments for voltage/size.
Application Scenarios
Electrical Distribution Equipment: High/low voltage power distribution cabinets, frequency converters, and distribution boxes—used for busbar connection, fixation, and insulation.
Industrial Electrical Systems: Factories, workshops, and commercial buildings’ electrical control panels—prevents short circuits and ensures stable power transmission.
Infrastructure Projects: Municipal power facilities, residential community power distribution rooms—meets large-scale installation needs with batch supply.
Frequently Asked Questions (Q&A)
Q: What’s the difference between SM-25 and SM-30 models? A: SM-25 has a diameter of 18mm, height of 25mm, and M6/M8 thread; SM-30 has a 32mm diameter, 30mm height, and M8/M10 thread. Choose based on busbar size and installation space.
Q: Can this insulator be used in outdoor or high-temperature environments?
A: Yes. The resin material resists high temps (no deformation) and low temps (no fracture), but it’s mainly designed for indoor electrical cabinets. For outdoor use, match with protective covers to avoid direct rain erosion.
Q: How to install the insulator? Do I need special tools?
A: It uses a connector mounting type—simply fix it via the brass thread with a standard wrench. No special tools are required, and the installation aligns with common electrical cabinet assembly processes.
Q: What customization services are available, and what’s the minimum order for customization?
A: Customizable services include logo printing, packaging design, and graphic printing—minimum order is 10,000PCS for these. For non-standard size/voltage adjustments, contact the supplier to confirm details.
Q: Why choose this insulator over porcelain alternatives?
A: It’s lighter (easier to transport/install), has better flame retardancy, and brass threads for longer service life. Also, it avoids "zero-value insulation" issues common in porcelain insulators, reducing maintenance frequency.
