Question

When it is better to use non-insulated end sleeves НШВ?

Answer

Mainly when you want to save some money. Sometimes when you need a heat resistant connection, for example, when you use cables with Teflon or organic-silicon insulation. Maximal operation temperature for insulated end sleeves with PVC or nylon cuff is no more than 150°C. When insulation is too thick and cannot be pushed inside the cuff, it is better to use non-insulated end sleeves. One more reason for the usage of non-insulated sleeves is a need to connect 2 or 3 cables. There is however a type of insulated end sleeve for connection of two cables, it is called НШВИ (2).
