HEKA 1/0,4 kV compact transformer substations

Our 1/0,4 kV compact transformer substation are particularly suitable for the supply of power to isolated consumers, such as those in rural properties, summer houses, facilities on archipelagos, or for anyone involved in winter sporting activities. The use of 1kV for the transmission line will greatly reduce transfer losses and improve voltage quality. The transformer substations are equipped with 0.4/1 kV and 1/0.4 kV dry transformers respectively, both of which have low loss and noise levels. The use of dry transformers will allow the positioning of the transformer substations in nature conservation areas or water catchment areas.

 

 

HEKA1VM70

Transformer substations rated at 0.4/1 kV and 1/0.4 kV for transformer output up to 70 kVA

 

DESIGN FEATURES

The substation enclosure is manufactured out of galvanised steel sheets and has powder-coated paint that is resistant to ultraviolet light. The HEKA1VM70 may be fi tted with transformers of 16, 30, 50 or 70kVA output, and can be equipped according to customer requirements. A single 1kV power supply cable with a cross-section of up to 50mm2 may be connected to the transformer’s primary coil connectors. Up to three outgoing groups with IEC size 00 NH-fuses may be connected to the secondary coils. The rail system is touch-proof (IP20) and is made by Kabeldon or Jean Müller. The cabinet doors can be fi xed in the open position. The transformer substation may be mounted on ground sockets or on a post. The post mat be fi tted with cable protection. As optional extras, the cabinets may be fitted with padlocks, “Stockholm locks”, fuses on the primary side, and the option to connect two incoming cables. The enclosure is painted in RAL7032 as standard.

HEKA1VM70

Transformer substations rated at 0.4/1 kV and 1/0.4 kV for transformer output up to 200 kVA

 

DESIGN FEATURES

The transformer substation is normally equipped with dry transformers of 0.4/1kV or 1/0.4kV respectively. Oil-fi lled transformers may also be used, and in such cases the substation will be equipped with an oil pan with enough capacity to collect all the oil in the transformer. The substation enclosure is manufactured out of galvanised steel sheets and has powder-coated paint that is resistant to ultraviolet light. The HEKA1VM200 may be equipped with transformers which have output levels up to 200kVA. A single 1kV power supply cable with a cross-section of up to 240mm2 may be connected to the transformer’s primary coil connectors. Up to fi ve outgoing groups with IEC size 2 NH-fuses may be connected to the secondary coils. The rail system is touch-proof (IP20) and is made by Kabeldon or Jean Müller. All live components are placed in their own sections which come with protective doors. The doors can be fixed in the open position. The unit is painted in RAL7035 as standard.
