About Jack

Founded in 1986, SAA Grid Technology Co., Ltd is a national high-tech enterprise and one of the most powerful composite insulator manufacturers in China. We manufacture the following products: 110kV-1000kV composite long rod insulators, 11kV-230kV composite line post insulators, 11kV-800kV composite station post insulators, 27.5kV composite railway insulators; surge arresters, drop-out fuse cutout, disconnectors and other electrical products.

Railway Insulator

Jack03 Nov, 2022Business

Insulators for railway traction applications are a different category from conventional insulators because they require extremely stringent performance and safety requirements. Modern insulators set the standard for the design, manufacture, testing and supply of insulators for railway traction applications. We manufacture various types of 25kV railway insulators to meet the various needs of electrification of railway lines.

Station Post Composite Insulator

Composite insulators are also called synthetic insulators, non-ceramic insulators, polymer insulators, rubber insulators, etc. The main structure is generally composed of umbrella skirt, glass fiber reinforced plastic mandrel and end fittings. Umbrella skirts are generally made of organic synthetic materials, such as ethylene-propylene rubber, high temperature vulcanized silicone rubber, etc.;

Long Rod Post Composite Insulator

Compared with traditional ceramic insulators, the use of polymer/silicon rubber-based insulators has several advantages, such as light weight, non-brittleness, hydrophobicity, resistance to ozone and UV radiation, seismic shock resistance, self-cleaning properties, and damage resistance.The exterior shed is moulded in rubber using the latest state-of-the-art injection moulding machines from .

11kV Polymer Suspension Insulator

Jack03 Nov, 2022Business

Like string insulators, suspension insulators are flexible insulator strings that are made up of some porcelain or glass disk insulators connected to each other by metal connectors. Widely used in medium and high voltage transmission lines.There are two types of suspension insulators: cap-pin insulators and interconnect insulators (also known as Hewlett-type insulators), which are two designs that are connected using different metal connections.

110kV Polymer Suspension Insulators

ERC high-temperature and acid resistant mandrel is used as the core rod of polymer suspension insulator, and the interface between the mandrel and silicone rubber is coated with special coupling agent. The umbrella cover adopts a one-time overall molding process under high temperature pressure, and a two-stage vulcanization process under computer monitoring to extend the service life.

Surge Arrester vs Lightning Arrester: Which One to Choose?

Jack26 Oct, 2022Business

1.The surge arrester will be installed nearer to the equipment to be protected and the transmission tower line enter in to the substation point.2. It protects against high voltage transient (example: lightning strike on the transmission conductor) typically, it is indirect protection of lightning strikes.3. It should be installed each phase of the circuit. i.e if you have 2 parallel switch yard then you should install 6 number of surge arrester (first run 3 phase and second run 3 phase) .

Composite Insulator Used For Transmission And Distribution Line

SAA Grid offers the most comprehensive range of porcelain line post insulator up to highest AC and DC system voltages with the most progressive technology, engineering and life time. Short production time, tighter tolerances, flexible design, extra-high mechanical strength and extended creepage distances are possible by isostatic process.

Long Rod Composite Insulator

Jack06 Jul, 2022Business

The composite long rod insulator, also known as: composite insulator or non-porcelain insulator, is a polymer insulator composed of at least two insulating parts, namely a core body and a jacket equipped with metal accessories. Long rod composite insulators are mainly used for suspension cables in linear supports and tension chords in anchor towers and dead-end towers. They are also used for jumpers or entrances in outdoor substations.

Ceramic Insulator

Jack06 Jul, 2022Computer & Internet

As a professional ceramic insulator supplier, SAA GRID offer different kinds of Station Post Insulator for Substation, Line Post Insulator, disc suspension insulator, etc. Ceramic Insulators are manufactured in various sizes and also as per customers requirement.Ceramic insulators are ceramic materials used to insulate electrically-conductive materials or temperature-controlled enclosures. In the context of electrical insulation, ceramic insulators are usually limited to the insulation of electrically conductive materials on an industrial or municipal scale.
