China BMC D-Series Low-Medium Voltage Standoff Busbar Insulator Suppliers & Factory Quality Solutions
D Type electrical hexagonal insulation parts introduction
Our product is crafted using unsaturated resin (BMC) as the core raw material. The metal inserts embedded within are typically made of galvanized iron. This material combination exhibits excellent performance in maintaining long - term stability, resisting high - temperature aging, and ensuring adequate structural strength, making it a perfect fit for industrial scenarios with exacting demands.
When it comes to the installation procedure, an installation torque of 10-30 N·m is usually recommended. The D - series unsaturated resin insulators are designed to offer your system dependable insulation protection, effectively minimizing the risk of system malfunctions and enhancing the overall reliability of your equipment.

Frequently Asked Questions (FAQ)
What materials are used in D-type hexagonal insulators?
Our D-type hexagonal insulators are manufactured using high-quality unsaturated polyester resin (BMC/DMC) as the primary raw material, with metal inserts typically made of durable brass or galvanized steel.
What is the recommended installation torque?
We recommend an installation torque of 10-30 N·m to ensure a secure connection without damaging the insulator body or the embedded metal inserts.
What temperature range can these insulators withstand?
These insulators exhibit excellent thermal stability and are rated for a working temperature range of -40°C to 140°C, with a hot wire temperature resistance of up to 960°C.
What certifications do your products have?
Our D-type insulators comply with international quality and safety standards, holding certifications such as UL (UL94 V0 Flame Retardant), CE, RoHS 2.0, REACH, IATF16949, ISO9001, and ISO14001.
Can the size and thread configuration be customized?
Yes, we support customization for thread sizes (M8-M10), product heights, diameters, and insert materials (brass/steel) to match your specific system requirements.
What is the Minimum Order Quantity (MOQ)?
The minimum order quantity for our standard D-type hexagonal support insulators is 100 pieces.
