Gaskets for Electrical Applications
RAM supplies gaskets for Electrical Applications, Electrical Transformers, SF6, Lighting, Marine Lighting and Window Gaskets in Electrical Applications.
Common Material types used in the Electrical sector are, rubber foams, solid and soft rubbers, EPDM, nitrile, neoprene, silicone, Softchem, cork, Nebar cork, EMI rated materials including nickel and silver plated, fluorosilicone and low out-gassing silicone.
RAM supplies gaskets for electrical enclosures worldwide.
Gaskets types used on electrical enclosures include door gaskets, front panel, access panel, gland plate and connector gaskets.
Glass/plastic windows on electrical products and components including marine and fluctuating weather environments require effective sealing.
Requirements for Electrical Enclosures
Electrical enclosures require longevity, with exposure to UV, ozone temperature, chemicals and mechanical wear all impacting the life of a gasket. Many enclosures may need to be vented to minimise condensation. Door latching on enclosures is critical regarding the material choice, the gasket material chosen must be properly compressed, with enough even pressure and not too much so that the gasket is over compressed. RAM ensures a quality product every time, allowing for the right materials to be supplied in the right situation and the shelf life and requirement of the gasket correctly specified.
Common material types for protection against specific elements.
|Protection Type||Material Used|
|Dust and falling dirt||Open or closed cell foams, with/without self-adhesive backing. Low density rubber.|
|Dust, dirt, dripping/light water splashing||Closed cell foams.|
|Windblown dust, falling dirt, water (rain, sleet, snow and ice formation).||Closed cell foams.|
|Indoor/Outdoor, falling dirt, windblown dust, water (rain, sleet, snow and ice formation).||Closed cell foams.|
|Indoor/Outdoor enclosure, falling dirt, settling airborne dust, lint, fibres and flying debris. Protects against water (rain, sleet, snow, splashing water and hose directed water and ice formation).||Closed cell foams, Cork|
|Indoor/Outdoor enclosure, falling dirt, settling airborne dust, lint, fibres and flying debris. Protects against water (rain, sleet, snow, splashing water and hose directed water and ice formation). Vibration/movement.||Cork – various types including nitrile cork, neoprene cork.|
|Indoor/Outdoor enclosure, falling dirt, water (hose directed water and entry of water during prolonged submersion at a limited depth and ice formation).||Closed cell foams low and mid durometer elastomers (soft rubbers). Cork|
|Indoor enclosure (w/o knockouts, 12K w/knockouts), falling dirt, settling airborne dust lint, fibers and flyings. Water – dripping and light splashing).||Closed cell foams. Cork|
|Indoor enclosure, falling dirt, settling airborne dust, lint, fibres and flying debris. Also protects against water (dripping and light splashing). Some protection against spraying/splashing/seepage of oil and coolants.||Chemical compatible closed cell foam. Silicone, nitrile, neoprene, polypropylene…..|
|SF6 – Gas Insulated Transformers||Cork, Nebar and Nitrile blends. Closed cell foams with/without SA backing.|
|EMI Shielding, silver, nickel and carbon fillers.||EMI rated gasket materials, Silicone, Fabric over foam, Fluorosilicone, EPDM. Low-outgassing silicone, Dense silicone 20 SH to 80 SH Hardness, Nickel-plated graphite and Silver plated Copper, Aluminium and Nickel.|
|Transformer Gaskets||Nitrile, nitrile cork.|
|Enclosure and screen seals/gaskets||Soft rubbers, self-adhesive foams, silicone, paper.|
Enclosure and Screen Seals
Enclosure and screen seals are a window shaped gasket. Many materials, shape sizes and density used to seal enclosures, electrical products, marine windows etc; generally, anywhere a weather seal is required and/or a glass/plastic screen requires sealing.
Global Weather Extremes
External enclosures require seals to withstand weather with weather types varying globally, temperature fluctuations in hot/desert countries. High rainfall and frost/snow. RAM are experts at sealing outdoors all year round for critical applications.
RAM supports designers and engineers creating lighting solutions. RAM will manufacture gaskets and seals to your requirement. Large installations, innovative lighting concepts, bespoke solutions for weather sealing installations, can all be sealed by RAM.
Projects include bespoke fittings, large scale design critical access and difficult/high risk environments.
RAM supplies weather seals, adhesive strips, packings, anti-vibration, high temperature and fire-rated materials for this kind of application.
