Our Ultratrac H950 GPO3 Polyester Glass Insulation Board is a high voltage electrical insulation material with good electrical properties, heat, arc and tracking resistance and excellent mechanical strength.
This rigid electrical insulation sheet material is made from a special polyester resin that is reinforced with omnidirectional glass fibres. The result is a tough, strong board that can be machined to tight tolerance and withstand large amounts of wear and physical stress.
Ultratrac H950 is produced by Haysite in the United States and is used in several different industries and applications. Many of its features and capabilities are expanded on below:
Manufactured by Haysite in the USA and trusted throughout the world, H950 Ultratrac meets or exceeds all the requirements for a NEMA GPO3 insulation material.
H950 has excellent flame resistance and has a UL recognised flammability rating of UL 94 V-0.
Arc protection and resistance is also very strong and has been tested in accordance with D-495 standards. In this test, H950 recorded an Arc Resistance rating of 194 seconds.
More information on these properties, as well as ignition times, smoke density and more is included on our comprehensive H950 Technical Data Sheet.
H950 is used in a variety of different electrical insulation applications due to its excellent electrical properties. In addition to the aforementioned arc resistance, H950 has good dielectric strength which is rated as:
H950 GPO3 Laminate has a maximum operating temperature of 160°C which makes it suitable for use in all Class F (or below) electrical applications.
As mentioned earlier, this material has excellent flame resistance and very low smoke generation which has led to its use in all kinds of underground and tunnel applications.
Our H950 GPO3 Insulation Board is extremely tough and strong. Made with a quality polyester resin, this material is suitable for machining to tight tolerance thanks (in part) to the omni-directional glass fibres that are scattered throughout the board.
These fibres reinforce the material in all directions and allow tight-tolerance machining without the threat of layer splitting that is seen in some other types of laminates. Below is a summary of some of H950’s physical properties, more are listed on the TDS.
