BILAG 4 Isolationsklasser og spændinger Jfr. Stærkstrømsbekendtgørelsens afsnit 6, Elektriske installationer. Definitioner for elmateriel: Materiel af klasse 0 Materiel, der kun har grundisolation som beskyttelse mod elektrisk chok. Materiel af klasse I Materiel hvor beskyttelse mod elektrisk chok ikke alene afhænger af grundisolation. Materiellet har desuden midler til forbindelse af de udsatte dele til beskyttelseslederen i den faste installation. Materiel af klasse II Materiel hvor beskyttelse mod elektrisk chok ikke alene afhænger af grundisolationen, men hvor der er anvendt dobbelt isolation eller forstærket isolation. Materiellet har ikke midler til forbindelse til beskyttelseslederen. Materiel af klasse III Materiel hvor beskyttelse mod elektrisk chok opnås ved, dels at materiellet forsynes med ekstra lav spænding, SELV eller PELV og dels at materiellet ikke selv frembringer højere spænding end ekstra lav spænding. Definitioner for spændinger Ekstra lav spænding (ELV) Enhver spænding, der ikke overstiger grænsen for spændingsområde 1 (d.v.s. 50 V vekselspænding eller 120 V jævnspænding) Side 60 af 62
BILAG 5 Materialer til elkontakter (eng.) Connectors (kilde: http://machinedesign.com/BasicsOfDesignEngineeringItem/714/65761/Connectors.aspx) Connectors are divided into four categories based on operating environments: commercial, industrial, military, and hermetic. In commercial applications, outside temperatures and atmospheric conditions are the least critical. Connectors merely maintain electrical continuity, allowing low-cost materials to be used. Industrial connectors are offshoots of commercial models for more rugged environments. Hazards include thermal shock, corrosion, vibration, physical jarring, and sand and dust. Military connectors are more reliable and withstand extreme environmental conditions. They are made to military specifications and are available from a variety of sources. Hermetically sealed connectors have performance requirements that are as rigid as military types. They are used in chemical-processing systems, industrial and commercial refrigeration units, and in underwater and aerospace electronic applications. Designers can select from several different connector materials: Brass Brass has excellent conductivity but cannot withstand many insertion and withdrawal cycles. Brass loses flexibility as it ages and under repeated stress is subject to crystallization, which significantly lowers conductivity. It is suited for noncritical, low-contact-force applications, and is easily crimped, soldered, welded, and brazed. Beryllium copper Beryllium copper has excellent mechanical, electrical, and thermal properties and resists corrosion and wear. It is the best electrical conductor of any spring alloy of comparable hardness. Beryllium copper is stronger, more resistant to fatigue, and withstands more insertion and withdrawal cycles than any other copper-base spring alloy. But its cost is the highest of the basic contact materials. Nickel-silver alloys Nickel-silver alloys are oxidation resistant, and do not always require plating. Nickel-silver is susceptible to stress corrosion, although not to the extent of brass. Gold Gold is an excellent conductor and a highly stable plating material. It has the lowest contact resistance and provides the best protection from corrosion. Hard gold platings are recommended for frequent insertion/withdrawal cycles. For even greater cycling, gold can be impregnated with graphite with a minimum increase of contact resistance. Side 61 af 62
