Abstract

ABRIGO DE ISOLADOR POSSUINDO UMA PONTA NÃO CIRCULAR. A presente invenção refere-se a um isolador para isolar eletricamente um condutor elétrico. O isolador compreende um rolo, definindo um furo de passagem longitudinal, central ao longo de um eixo longitudinal do isolador. O furo de passagem é disposto para permitir que um condutor elétrico passe por ele. O isolador também compreende pelo menos um abrigo (2), disposto em uma superfície externa do rolo. O abrigo compreende uma ponta de abrigo (10) possuindo uma curvatura (11) não plana , definida por uma pluralidade de diferentes raios de curvatura e compreendendo um ponto mais distal do abrigo. Um raio de curvatura de extremidade (R), no ponto mais distal da curvatura, é maior do que um primeiro raio de curvatura (r1), em um lado do ponto mais distal, e de um segundo raio de curvatura (r2), no outro lado do ponto mais distal.
