Introduction

TUW4710 insulation gas is a sustainable alternative to sulfur hexafluoride (SF6), which has excellent dielectric properties, a wide operating temperature range, and can significantly reduce its impact on the environment compared to SF6. TUW4710 gas is non flammable and has a wide range of safety limits when designed for use in intended applications. Compared to using SF6, mixing TUW4710 gas with inert gas can significantly reduce greenhouse gas (GHG) emissions from gas insulated equipment.

Product characteristics

Features: colorless, odorless, safe and non-flammable, ODP value is zero, no damage to the ozone layer,excellent material compatibility, high safety.

Advantages: excellent dielectric properties, a wide range of operating temperatures andsignificant reductions in environmental impact compared to SF6. Dielectric breakdown voltage approximately 2 times that of SF₆ at a given pressure. At the sametime,TUW 4710 gas enables a significant and meaningful reduction in greenhouse gas (GHG) emissions from gas-insulated equipmentcompared to using SF₆.

Product usage scope

Insulation and arc extinguishing for medium and high voltage power generation and distribution equipment, including gas insulated switchgear, gas insulated circuits, and circuit breakers.

Product storage and transportation

TUW4710 should be stored in a clean, dry warehouse, away from direct sunlight, and kept away from high temperatures, strong alkalis, etc. High pressure gases are prone to explosion when exposed to heat.

TUW4710 is a colorless and transparent gas. During transportation, it should be avoided from violent oscillation, and when stacking, it should be avoided from being inverted.

Pay attention to the sealing of TUW4710 products during storage and transportation.
