SUBMERSIBLE TRANSFORMERS

PAG 8

These submersible transformers are available in capacities of up to 3000 KVA

for three-phase transformers and up to 500 KVA for single-phase transformers.

High voltage rating up to 34,5 GrdY/19.92 KV and 150 KV BIL.

These units are designed to operate in a chamber or under ground level vault

and subject to maximum possible flooding period of 24 hours under a water

column of 40 cm above the top of the transformer.

Theses transformers are equipped with substation elements in order to protect

the equipment:

Failures in the secondary network and external overload by means of

interchangeable bayonet type removable fuses.

Failures in the primary network by means of elbow arresters.

In addition, the transformer protects the primary network of high current faults

in the windings by means of current limiting fuses or backup isolation link.

These transformers can be supplied with one of the following configurations:

Radial configuration: End of medium voltage circuit, with load switch open-

closed.

Loop configuration (To continue the medium voltage circuit) with 4-position

switch.

These transformers are manufactured in compliance to: ANSI C-57.12.23,

ANSI C-57.12.24, NTC 4406 and RETIE standards.



DRY TYPE TRANSFORMERS

Low voltaje dry type transformers

Medium voltage dry type transformer

PAG 9

Single phase and three phase transformers with power ratings from 1KVA up to 500KVA, and voltages levels of up to 600 volts. These units are designed to operate indoors (enclosure with IP20 protection) or outdoor (IP23 protection cabinet). These units are cooled by natural circulation of air and have self-extinguishing high temperature insulation (class H-180°C) to reduce the risk of fire in case of external events, short circuit or overvoltage. Used in residential, commercial or industrial applications, with optimum efficiency, low loss and low noise level. These units are manufactured in compliance with NTC 3445 standard.

Air-cooled three-phase transformers, manufactured from 75KVA up to 630 KVA with standard voltage ratings of up to 15KV. Its active part is designed with copper or high-purity aluminum windings and stack core grain oriented silicon steel with low losses, allowing it to withstand the high temperature levels to which the transformer is exposed to when connected to a load. These units have self-extinguishing high temperature insulation (Class H-180 ° C) to reduce the risk of fire in case of external events, short circuit or overvoltage. These transformers are useful for raising or lowering voltage levels, in residential, commercial or industrial applications. Rymel´s dry-type transformers offer optimum efficiency, low losses level, and minimum noise levels.

Advantages and Applications:

Due to its lower weight (compared to an oil unit) it allows to be located inside buildings and/or elevated floors.

Its Self-extinguishing insulating material allows the dismissal of fire-proof rooms.

These units have a cheaper construction permit and their maintenance is easier compared to oil immersed transformers.

These transformers have no tank, given the fact that they are located in a substation cabinet.

Used in places where we want to minimize the environmental impact caused by insulating liquids.

WILDLIFE PROTECTOR COVER


It is a device for protecting live parts of the terminal insulators bushings in different equipment installed in the power distribution system and which may be exposed to potential contact by animals or people.

This wildlife protector cover is used in the insulators installed on distribution transformers, regulators, switches, load break switches, lighting arresters, and others to prevent birds, reptiles, rodents and other animals to cause short circuits or faults between phases or between phase and earth that could affect the quality of service and increase the costs of operation and maintenance. It is made of a material which is resistant to ultraviolet radiation, tracking, abrasion, shear, to carbonization, to cracking and deposition of feces of animals, it has high impact strength (not less than IZOD of 160.1 Joule / m), has a maximum water absorption capacity of 0.09% by weight and a minimum dielectric strength of 300V / mL. It aims to increase the insulation level of the structure and increase the leakage distance phase to earth.
