Fiberglass doors Ventilation grids
The doors in fiberglass (fiberglass), from one to four doors (also more) are made to allow access to the interior of prefabricated structures and ensure the safety of the prefabricated substations themselves, according to E-distribuzione DS1511 technical specification.
The doors in fiberglass (fiberglass), from one to four doors (also more) are made to allow access to the interior of prefabricated structures and ensure the safety of the prefabricated substations themselves, according to E-distribuzione DS1511 technical specification. They are prepared for the assembly of E-distribuzione DS988 type locks with closing to one or three points. The material is polyester resin reinforced with SMC self-extinguishing fiberglass according to E-distribuzione DS 4974 and have a degree of protection IP 33 according to IEC-EN 60529 and IK10 according to CEI-EN 50102.
Le porte in metallo / lamiere sono realizzate in caso di necessità in più ante secondo le varie esigenze e consentono l'accesso all'interno delle strutture e garantiscono la sicurezza delle stesse. Il materiale è in lamiera zincata a caldo prerivestita spessore 15/10 pressopiegate con cerniera in alluminio presso fuso per consentire l'apertura dell’anta a 180°. Hanno resistenza alle correnti superficiali secondo norme IEC 60112 - PTI 500, alla fiamma secondo prescrizioni in Classe 0. Le porte, da una a quattro ante.
Le griglie di areazione sono installate per l’areazione di cabine elettriche secondarie di media e bassa tensione (MT/BT), sono autoestinguente e realizzate secondo le prescrizioni E-distribuzione DS 4974 in resina poliestere rinforzata con fibra di vetro SMC. Sono conformi alla specifica tecnica E-distribuzione e Hanno un grado di protezione IP 33 secondo la norma CEI-EN 60529. Sono corredate di rete anti-insetto in acciaio inox con maglia da 10x10mm e di accessori per il montaggio. Con la progettazione delle cabine, vengo disposti le griglie in modo da fornire sempre il giusto equilibrio termico all'interno delle strutture prefabbricate.
Foundation tank prefabricated base
The foundation tanks in work is a bearing surface inside of an excavation for the positioning of a base, on which are laid the prefabricated electric prefabricated substations. The prefabricated base, made on site, has a minimum size of 1500 mm to 7500 mm (L) x 2500 (W) x 600 (H).
The tank, in addition to the isolation of the product from the ground, has holes at pre-established fracture to allow the 'input of cable ducts and the passage of cables of medium and low voltage for the internal distribution. It can be equipped with preassembled cable gland kit for MV and LV incoming and exiting cables from the enclosure box, suitable to guarantee the requirements of tightness even in the absence of cables passing through. The outer grounding system is constituted by a copper braid of suitable thickness, positioned inside the trench around the perimeter of 1 meter from the crankcase connected to the electro-welded network drowned in the crankcase, from the point of the ground inside the prefabricated substation and by 4 cross ground conductors driven into the ground adjacent to the corners of the base.
The tank is able to totally recover during the shift phase and collects transformer oil, in fact for the possible leakage of transformer oil you can request a complete base with flange that ensures the seal both inside and outside.
MV electrical switchboards
The electrical panels used by Eurostructures are of primary brand and comply with the CEI 016 second edition standard. The offer is divided into 2 groups, namely panels with directional earth protection (67N) and data logger or panels with undervoltage relays. They are modular, easily coupled and equipped with more accessories on request. Delivery times are relatively short. Some of the types of paintings most frequently used in our most important works are illustrated below.
Electromechanical compartments with undervoltage relay
Base compartment, one complete compartment with voltage presence on busbar side and circuit-breaker cable side in SF6 or in vacuum with manual command, shunt opening release, shunt closing release, operation counter, auxiliary contacts 2NO + 2NC, undervoltage release, trip signaling contact. de-energized
