Product Description

Low Voltage BMC Bus Bar Support Insulator

This low voltage bus bar support is molded from bulk molding compound (BMC) reinforced with chopped fiberglass, giving a rigid, dimensionally stable insulator that holds copper and aluminium busbars in position inside distribution boards, panelboards and switchgear cabinets. A moulded-in M8 brass insert takes the fixing bolt directly, so no separate nut, spacer or tapping operation is needed during assembly.

Quick Detail

Product Name	Low voltage BMC bus bar support insulator
Model Number	SC-LVB40
Material	BMC (bulk molding compound), fiberglass reinforced, halogen free
Height	40 mm standard; 25 / 30 / 50 mm available
Insert	M8 brass insert, moulded in, torque 8 N·m
Rated Voltage	Up to 1000 V AC / 1500 V DC
Colour	Grey, white, black, red or customer colour
Application	Busbar support in LV switchgear, distribution boxes, capacitor and inverter cabinets
OEM	Dimensions, insert thread and colour made to drawing

Technical Specification

Dielectric strength	≥ 12 kV/mm (dry, 1 min)
Comparative tracking index (CTI)	≥ 600 V, class PLC 0
Flame retardancy	UL 94 V-0
Arc resistance	≥ 180 s
Insulation resistance	≥ 1.0 × 10¹² Ω at 500 V DC
Flexural strength	≥ 120 MPa
Impact strength (Charpy, unnotched)	≥ 45 kJ/m²
Water absorption	≤ 0.20 % (24 h)
Operating temperature	-40 °C to +155 °C
Busbar thickness range	3 mm to 12 mm, single or double bar
Reference standard	IEC 61439-1, IEC 60695, RoHS compliant

Why This Bus Bar Support

One-step assembly: the moulded-in M8 brass insert accepts the fixing bolt directly and holds 8 N·m without thread stripping or creep.
Safe creepage distance: the ribbed body and 40 mm height keep live busbars clear of the mounting plate, with CTI 600 V class PLC 0 tracking resistance for polluted panel interiors.
Fire retardant and non-conductive: UL 94 V-0 BMC body will not support combustion and adds no conductive path if an arc occurs.
Stable under heat and humidity: low shrinkage, water absorption below 0.20 % and continuous service to 155 °C, so clamping force does not relax over the panel lifetime.
No corrosion, no maintenance: fibre reinforced compound is acid, alkali and moisture resistant and will not rust, unlike steel or aluminium standoffs.
Made to your drawing: height, body diameter, insert thread (M6 to M12), slot spacing and colour can all be tooled to match an existing part number.

Typical Applications

Low voltage distribution boards and consumer units
Panelboards, MCC and control cabinets
Capacitor banks, inverters and UPS enclosures
Busbar chambers in modular switchgear and meter boxes
Battery racks and DC power distribution frames

Quality Control

Each batch is checked for insert pull-out force, thread torque, dimensions and appearance, and flash-over tested on sample parts before packing. The factory operates an ISO 9001 quality management system and can supply material and test reports with the shipment.

FAQ

Q: Can you produce this support to our drawing?

A: Yes. Send the drawing or a sample, we will quote the tooling and the unit price, then produce samples for approval before the bulk order.

Q: What is the MOQ?

A: 1000 pieces for standard sizes. Smaller trial quantities are accepted when the size is in stock.

Q: What are the payment and delivery terms?

A: Basically T/T 30 % with the order and the balance before shipment. Normally 7–20 working days after deposit, depending on quantity.

Q: How is the product packed?

A: PE bags inside export cartons on pallets, or per your packing instruction.

Contact us with your busbar size and panel type, and we will recommend the correct support height and insert thread the same day.
