Medidas das abra\u00e7adeiras de cablagem: tabela de comprimento, di\u00e2metro do feixe e resist\u00eancia<\/h2>

Para escolher a medida de uma abra\u00e7adeira de cablagem s\u00e3o necess\u00e1rios dois valores: o di\u00e2metro a apertar, que determina o comprimento, e a carga a suportar, que determina a largura. As abra\u00e7adeiras<\/a> COBRA standard em nylon PA6.6 v\u00e3o de 80 x 2,4 mm (\u00d8 m\u00e1x. 17 mm, resist\u00eancia de 8 kg) a 1500 x 9 mm (\u00d8 m\u00e1x. 460 mm, resist\u00eancia de 79,8 kg).<\/p>

A regra: o comprimento determina o di\u00e2metro, a largura determina a resist\u00eancia<\/h2>

Na gama standard, cada largura tem a sua pr\u00f3pria resist\u00eancia, ao passo que, ao aumentar o comprimento da abra\u00e7adeira, aumenta o di\u00e2metro m\u00e1ximo de aperto.<\/p>

Mesmo comprimento, resist\u00eancia quase sete vezes superior<\/h2>

Tomemos o comprimento de 200 mm: aperta di\u00e2metros entre 49 e 53 mm, mas a resist\u00eancia sobe de 8,1 para 54,4 kg consoante a largura. Quando a aplica\u00e7\u00e3o est\u00e1 sujeita a vibra\u00e7\u00f5es ou a esfor\u00e7os elevados, verificar a largura da abra\u00e7adeira \u00e9 a chave para uma cablagem fi\u00e1vel.<\/p>

Como escolher em quatro passos<\/h2>

1. Me\u00e7a o di\u00e2metro a apertar.<\/h3>

Escolha uma abra\u00e7adeira com um di\u00e2metro m\u00e1ximo de aperto superior ao do objeto a fixar, deixando uma margem que facilite a pega da ponta livre durante a instala\u00e7\u00e3o. Se prev\u00ea acrescentar mais cabos, tenha em conta desde logo o di\u00e2metro final e n\u00e3o se esque\u00e7a do dente de pr\u00e9-engate presente nas nossas abra\u00e7adeiras Cobra.<\/p>

2. Avalie a carga.<\/h3>

Para cablagens ligeiras, considere uma largura de 2,5 mm (8,1 kg); para tubos, calhas ou feixes pesados, passe para 7,6 mm (54,4 kg) ou 9 mm (79,8 kg).<\/p>

3. Avalie o ambiente de utiliza\u00e7\u00e3o.<\/h3>

As abra\u00e7adeiras standard em PA6.6 t\u00eam uma temperatura de servi\u00e7o de \u221240 \u00b0C a +85 \u00b0C e devem ser instaladas entre \u221210 \u00b0C e +60 \u00b0C. Escolha o natural para ambientes interiores e o preto, que cont\u00e9m carbon black, para aplica\u00e7\u00f5es no exterior. Para condi\u00e7\u00f5es de utiliza\u00e7\u00e3o especiais, est\u00e3o dispon\u00edveis abra\u00e7adeiras com caracter\u00edsticas t\u00e9cnicas espec\u00edficas.<\/p>

4. Escolha a embalagem.<\/h3>
