the function of insulator Why will we call them post insulators? Post porcelain insulator is a special insulation products in the electric system, which can play an essential function in overhead transmission line. We are a porcelain post insulator manufacturer in China. In the early years, post porcleain insulators have been mainly used for power […]


Does the post insulator need thermal stability verification?

0 Comments

No need! You don’t need to pay attention more on the thermal stability of porcelain post insulator. Because the fact there’s most effective one point connection among the submit insulator and the heating conductor, and typically, the fast-circuit modern of 35kV distribution isn’t big, the quick-circuit calorific value will not affect the mechanical performance of […]


How to protect grounding from lightning strikes? by lightning arrester

0 Comments

You need the products of surge arrester for it. Lightning protection grounding includes two concepts. One is lightning protection, which prevents equipment damage caused by direct lightning strikes. Second, electrostatic grounding, lets electrostatic go into the underground, this will ensure the normal work of electrical equipment and personal safety. The grounding device is composed of […]


Characteristic of porcelain insulator

There are many types of porcelain insulators. We can produce them according to IEC standards, BS standards, DIN standards, etc. Butterfly and pin porcelain insulators are mainly used in high and low -voltage transmission lines, while suspension insulators are used in high-voltage transmission lines. Porcelain insulators/ Ceramic insulators are a special insulation control, which can […]


What are the advantages and disadvantages of a single break isolator over a double break isolator?

0 Comments

Double end break switches similar to this switch: There are the following advantages over single end break switches: Improved swing arm stability for the higher voltage switches over 300 kV. Since the switch blade pivots in the center and breaks at both ends, the horizontal rotation is inherently more stable with regard to mechanical vibration.Improved […]


TEST SWITCHES AND ACCESSORIES

Test switches is designed and manufactured to allow quick and easy multi-circuit testing of switchboard relays, meters and instruments by any conventional system. These test switches and related test plugs have the features necessary for applications involving the measurement of individual currents and voltages associated with substation instrumentation and protection devices. To learn more about […]


What is the difference between onload and off load switch disconnectors and what is the type of INS switch ?

0 Comments

On load switch disconnectors:it is switch disconnector that can open and close the circuit on load and perform the isolation required. Off Load switch disconnectors:It is switch disconnector that must open and close the circuit when load is off (it can not operate on nominal load) – For example – Earthing switch used with CB […]


What is Composite Insulator?

0 Comments

A composite insulator is a special insulation control component that plays an important role in overhead transmission lines. There are many types of polymer insulators. What is Composite Insulator Made of?Composite insulator is also called synthetic insulator, non-ceramic insulator, polymer insulator, rubber insulator, etc. The main structure is generally composed of umbrella skirt, FRP core […]
