Post Insulator Busbar Support Insulator 12 kV 24 kV 40.5 kV
Serie de izolatores de suport pentru coloane si bare conductoare sunt componente izolante din rezina epoxidica concepute pentru echipamentele de comutatie de medie tensiune la 12 kV, 24 kV si 40,5 kV. Fabricate prin tehnologia de turnare APG, aceste izolatoare de suport prezinta o matrice epoxidica densa, fara goluri, cu fuste alternante adanci pentru distanta de curgere, asigurand o rezistenta ridicata la strapungere. Insertii filetate din alama integrate la ambele capete permit montarea sigura si standardizata a barelor conductoare. Disponibile in mai multe dimensiuni si inaltimi, aceste izolatoare de suport pentru bare conductoare sunt potrivite pentru panourile de tip KYN28, HXGN, RMU si GIS, oferind o performanta dielectrica fiabila in medii cu umiditate ridicata, continand sare si temperaturi extreme, frecvent intalnite in instalatiile din Orientul Mijlociu.

Epoxy Resin Post Insulator - 12kV / 24kV Busbar Support
Post insulators mechanically support medium voltage busbars while electrically isolating them from the earthed steel enclosure. They carry the weight of the copper busbar run continuously, and must also withstand the violent electromagnetic forces generated during a short circuit without cracking or allowing the busbar to move. MOLDVOLT manufactures 12kV and 24kV post insulators using APG casting, to IEC 60168 and IEC 62217.
APG CASTING - WHY THE PROCESS DETERMINES SERVICE LIFE
Automatic Pressure Gelation injects resin into a heated mould under pressure and gels it progressively from the mould surface inward. The result is a void-free, high-density matrix with consistent mechanical properties.
Vacua sunt inimici. Vacuum gas-plenum intra epoxidum fusum in regione stress electrici concentrati sedet, et ad tensionem operativam incipit interna descensio. Quisque descensio paululum resinam circumiacentem erodit. Isolator perfecisse probatur ad deliversionem, sed post quinque aut decem annos in usu deficit — longe post tempus garantiae, et saepe cum busbar et tabula simul. Ideo omnis isolator a nobis productus testatur pro descensione partiali, typice infra 10 pC ad 1.1× tensionem nominalem, non modo inspicitur visu et mittitur.
EPOXY CYCLOALIPHATICUM — ELECTIO MATERIALIS PRO CLIMATIBUS RIGOROSIS
Nos specificamus resinam epoxidicam cycloaliphaticam potius quam resinam bisphenolicam ad usum generalem. Resina cycloaliphatica resistit multo melius tractationi superficiali et degradatio UV, quae res permittit eundem componentem uti in statione subterranea litorali Golfi cum temperatura 55 C et sale, in installatione humidissima Africae Occidentalis, et in tabula Siberiana cum temperatura -45 C, per totum intervallum operationis a -40 C usque ad +105 C. Resina bisphenolica est minus cara et omnino sufficit in loco commutativo pulcro, arido et temperato — sed omnino insufficiens in ambientibus in quibus mercatus nostri reapse operantur.
CLASSIS MECHANICA
Onus cantilever nominale variat ab 1000 N usque ad 2500 N secundum typum. Electio regitur pondere catenae busbar, spatiis inter supporta, et corrente cortocircuitus prospecta, quia vis electromagneticus inter fases adjacentes durante defectu potest esse multoties maior quam onus staticum. Specificare tantum per tensionem, absque verificando robur cantilever contra gradum defectus, est error communis.

- Reservae pro fabricantibus tabularum et officinis pro machinis interruptivis.
CUR HOC EST SPARE ALTAE PETITIONIS
Insulatores postales laeduntur dum tabulae inspiciuntur, rimis scinduntur propter vires curtocircuitus, et degradantur propter pollutionem in regionibus litoralibus et industrialibus. Quia sunt structurales, insulator ruptus tabulam ex servitio tollit donec substituatur. Rara suppetitia partium reservatarum semper ut causa principalis in mercatis electricis Medii Orientis et Africae indicatur; ideo nos typicos in magazino tenemus et subministramus etiam substitutiones emergentiales singulares ac volumina productionis massivae.
Indicium Selectionis
Specificare oportet per quattuor parametres simul, non per tensionem tantum: tensionem nominalem et BIL, onus nominale cantilever contra vim curtocircuitus prospectam, interfaciem montandi et altitudinem, atque gradum pollutionis in ambiente installationis. Pro locis litoralibus in Sinu Persico et in Africa Occidentali, specificare oportet crepaginem prolongatam.
Congruentia Regionalis
- Medius Oriens: alta radiatio UV, alta temperatus et nebula salina litoralis faciunt resinam cycloaliphaticam et crepaginem prolongatam rectam specificare.
- Africa: humid coastal and industrial pollution environments; high replacement demand across an aged installed base.
- Russia and CIS: -40 °C to -60 °C service requires verified low-temperature mechanical performance, since epoxy embrittles as temperature falls.
- Eastern Europe: standard IEC 60168 service in temperate conditions.

POURQUOI CELA A DE L'IMPORTANCE COMMERCIALE
L'expertise technique locale limitée et la difficulté d'approvisionnement en pièces de rechange sont constamment identifiées comme les principaux obstacles sur les marchés électriques du Moyen-Orient et d'Afrique. Un tableau est hors service pendant toute la durée nécessaire à la livraison de la pièce. Nous gardons les articles consommables en stock et fournissons des listes de pièces de rechange pour flotte basées sur votre parc installé, afin que la pièce soit disponible avant même qu'elle ne soit nécessaire.
Quantitas et tempus ducens
- Articles en stock expédiés depuis l'inventaire ; délai de production typique de 15 à 25 jours pour les spécifications standard.
- Faibles quantités minimales de commande pour les pièces standard — nous fournissons des remplacements d'urgence unitaires ainsi que des volumes de production en gros.
- Fractura aeria pro situationes de defectu, fractura maritima per consolidation pro restockage planificatu.
Testatio et Documentatio
- Testes routine secundum standard IEC applicabile, con resultatus fornitu per batch.
- Certificates de material, reportus de spessore de plating e registros de inspectione dimensional disponibile super requestu.
- Supporto pro certificatione pro submissiones SONCAP, KEBS PVoC, SABER e GOST R, ubi le componente es expedito como un consignation independente.
Post-Venditio

Moderatio Materiae
- Cuprum verificate como cuprum electrolytic T2 o como alloy specificate de cuprum-argento, con certificates de mille retinute per batch.
- Epoxy resin verificatus est ut gradus cycloaliphaticus, cum tempore gelationis, viscositate et ratione pigmenti documentatis; resina bisphenolica ad usum generalem non admittitur pro servitio extra aedem aut in humiditate alta, ob deteriora eius resistencia ad formandos tractus et ad radiationem ultraviolettam.
- Spissitudo placationis mensurata est per fluorescencem radii X et annotata pro singulis partibus — typice 8–12 microna argenti in superficiebus contactuum. Sub-placatio non apparet in momento traditionis et solum post annos manifestatur ut defectus thermalis; ideo haec mensuratur, non supponitur.
Processus Imperium
- Fusio APG (Automatic Pressure Gelation) sub temperatura formae, pressione injectionis et tempore gelationis regulatis, producens matricem sine vacuitatibus. Vacuitates initiant descensum partiale, quod est causa ultima perforationis isolatoris in usu.
- Exsiccatio sub vacuo resinæ ante injectionem, ut aer inclusus tollatur.
- Ciclus post-curationis regulatus ad tensiones internas minuendas et dimensiones stabilizandas.
- Contactus digitus molla vis calibrata et verificata ad specificatio, ut currentis aequa distributio per omnes digitos certificetur.
