PRODUCT FAQ
-
What is 3M™ Cold Shrink Insulator 8448-A-ATH-(M), 50/Case?
3M™ Cold Shrink Insulator 8448-A-ATH-(M) is an insulating material that helps prevent electrical arcing and flashovers. It provides reliable weather resistance, moisture sealing, and erosion protection.
-
What are the benefits of using this product?
The main benefits of using the cold shrink insulators include ease of installation without special tools or heat, excellent protection against UV radiation and ozone, as well as a high degree of flexibility.
-
Are there specific applications for which this product has been designed?
Yes. This cold shrink insulator is primarily designed to provide insulation at terminations in three-phase MV-HV cables up to 72 kV where space constraints make it difficult to use conventional methods like resin casting. However, it can be used in other demanding environments such as underground mines or offshore oil rigs too.
3M™ 8440 Series Cold Shrink Silicone Insulator is an insulating sleeve made from high-temperature silicone rubber. It is specially formulated to maintain flexibility and pressure, even after years of aging and exposure. This insulator is designed to provide top moisture sealing for medium-voltage, air-insulated connectors and lugs.
Additionally, the 3M™ 8440 Series Cold Shrink Silicone Insulator offers resistance against acids, alkalis, fluid splashes, ozone, ultraviolet light, and fire. This makes it an ideal choice for use in sheath repairs and electrical aircraft cables. It also provides insulation for inline conductor transition connectors.
This insulator is RoHS 2011/65/EU Compliant, ensuring that it meets the highest standards for environmental safety.
