Indoor their can be used. Outdoors this type of installation material (tie) use is not recommended, they can be replaced with copper wire. Caps and vtulkiPri installation of neon tubes should be borne in mind that the distance between contact between the electrode and high-voltage wire (cable) with a grounded metal surface must be at least 20 mm, while protecting the contact silicone cap (insulator). Electrode Silicone caps (insulators) prevent ingress of moisture, oxidation of the contact at the junction of the electrode and high-voltage wire (cable). Also prevent the occurrence of the arc – “crown” of high-voltage connection between the wire electrodes and surface . condition for safe operation of the signs is a long-term protection from exposure to high voltage.

With this task successfully cope silicone caps (Insulators). They are made on the basis of silicone rubber, which retains a high koronostoykost, (the ability for a long time to resist the destructive action of ionization. Due to the high stability of this material to the effects of solar radiation and atmospheric humidity, the ability to maintain the constancy of the elastic properties at temperatures from – 60 to + 200 C, non-combustibility, silicone caps (insulators) are important insulating components required for use in the manufacture of neon signs. When you select should be considered to cover (insulator), as closely as possible “sit” on the electrode, thereby eliminating the possibility of moisture on the contact electrode and high voltage cable. Silicone caps (isolators) are available with different diameters. Previously used in the 80 years of 20 century caps made of pvc plastic under the action permanent high voltage quickly “age”, there is the formation of microcracks, which makes it possible to fire not only of the caps, but also signs. In addition, the leaching of plasticizers frost resistance of polymeric materials creates additional problems in the operation of neon signs in conditions of high humidity and temperatures. High-voltage wire (cable) high-voltage wire (cable) with Silicone insulation favorably with other wires. With its high property koronostoykosti, silicone stores it in a temperature range from – 60 to + 200 C and is a reliable heat-resistant insulating material suitable for the manufacture of mounting high-voltage wires. The impossibility of electrical breakdown is achieved the required insulation thickness (2-3 mm) without prejudice to the elasticity of the wires. In addition, silicone insulation has an electrical resistance 22kV/mm. Electrical breakdown is directly related to the voltage, the distance between the conductive housing and a grounded metal surface signs, insulation thickness, and its the main characteristic – permittivity.

Therefore, to avoid output wires down due to electrical breakdown, should strictly adhere to the parameters of the voltage and method of installation, recommended by the manufacturer. As producer of economic considerations, for the wire itself selects the brand and content, respectively, the rubber compound, the life of the wire may vary several times. Less filled with insulation lasts longer. To determine the fullness of wire insulation is enough to look at the cut wires, porous surface is unacceptable for high-voltage wires. When passing high-voltage wire near the grounded metal surfaces must be used under the wire holders, which create the necessary air gap of -10 mm. When laying high-voltage wires to maintain the distance between adjacent wires of 20 mm. When passing the wire through the metal surface is necessary to use silicone sleeves under the wire. Adhering to these recommendations are not saving on the purchase quality components and without violating the technology installation of neon signs, you can make objects neon signs are not only beautiful and attractive, but safe.
