Importance of the right kind of material for the standoff insulator
The material that is used in a glastic standoff insulator greatly influences its performance in certain applications. Different insulators are offered by manufacturers in the market like porcelain insulators that are made from clay, quartz and feldspar rock. These insulators are known for their abilities to tolerate high voltage and electrical stress with the reliability to regulate the flow of charge. Porcelain has high tensile strength and high resistance to corrosion and deformation; however, due to its rigidity, porcelain has the tendency to fracture. Plastic insulators are also versatile and they are cheaper than ceramics and composites but prolonged exposure to UV light can increase its frailty and result into the insulator shattering. An option is the composite laminate that makes use of fiberglass that provides greater physical flexibility and moisture resistance. An example of a fiberglass-based insulator is glastic standoff insulator that is highly versatile and tends to be more cost effective due to its numerous advantages.
Applications of a standoff insulator
A standoff insulator is mounted at a specific distance from the electrical component it will support. It functions essentially as a threaded spacer. The most important specification of a standoff insulator is its electrical clearance, mechanical strength and mounting procedure. The glastic standoff insulator is primarily intended to be used indoors or inside a suitable enclosure if it is used outdoors. It can withstand rated voltage continuously but there are industry standards and specifications that may require a different spacing from conductor to the ground for a particular voltage.
Standoff insulators are typically used for regulating currents in conductors or in conductive components of switchgear and transformers. Due to the physical separation between the insulator and component, the standoff insulator usually controls the flow of a high level of voltage. This will significantly reduce the chances of inter-component shortage. This is particularly important for powering stations or electrical devices that have energy requirements and electric-sensitive equipment.
In deciding whether the standoff is appropriate for a particular application, it is important to consider the insulating material and conductive strength including environmental conditions. Factors like function and electrical safety should also be a priority. Electrical insulators usually have strongly bonded valence electrons that prevent them from entering an excited state; however, if sufficient voltage is applied, the electrons can overcome their bonds and become charged. This may cause the insulator to become a conductor. Some form of material damage may occur on the insulator that can alter its physical properties. It would be helpful to review the electrical operations and the insulator that will suit the requirements before starting a project.
