The protective property of polymer-type fuse cutout is also called melting property. When the current exceeds the specified value, it uses the heat generated by itself to fuse the melt and break the circuit. The function of polymer type fuse cutout in the circuit is over-current protection, which can also be called short-circuit protection. Next, let's take a look at the operation precautions and operation and maintenance of polymer-type fuse cutout. Here are some answers.

A cold-shrinkable tube generally refers to tubular cable accessories using cold-shrinking technology, which has the functions of insulation, sealing, and protection. At present, cold shrinkable tubing is divided into Silicon Rubber cold Shrinkable Sleeve and EPDM cold shrinkable tubing according to the main raw materials for manufacturing. They are made of silicone rubber and EPDM respectively. Next, let's take a look at the introduction of Silicon Rubber cold Shrinkable Sleeve. Here are some answers.

The metal oxide surge arrester (MOSA) is a comparatively inexpensive component within a modern power system. Typically, it is specified, purchased and installed but later often overlooked when planning condition monitoring of assets in a substation.

Because of increasing difficulties in securing approvals for new transmission corridors, various new technologies for line uprating have been developed and are now being implemented. The basic idea is to use existing line corridors to transfer more power.

In an HVAC cable, electric field distribution depends on capacitances, which are dominated by permittivity of the insulation material that is stable with temperature. A specified is therefore not required when testing such cables.

Power system engineers all face a similar dilemma at one time or other when trying to identify which product offers the quality they require – especially in today’s global market with its many competing suppliers.
